However, age analysis of Late Cretaceous Argentinian bentonites and associated volcaniclastic rocks from Lago Pellegrini, Northern Patagonia, indicates that, in the case of these very low-permeability rocks, the radioactive 40 Ar was retained and thus can provide information on smectite age and the timing of rock alteration.

The use of low-cost clay materials for the fabrication of ceramic membrane has attracted much interest from researchers, and the outcome would be beneficial to the industries. In this study, low-cost bentonite was used for the preparation of hollow fiber ceramic HFC membrane.
Bentonite powder was initially characterized by field emission scanning electron microscope FESEM for powder surface morphology. The bentonite membrane was fabricated through dope suspension mixing, using phase inversion-based extrusion method and sintering processes. The dope suspension was prepared by mixing quantified bentonite powder, dispersant, polymer binder, and organic solvent on a planetary ball mill. FESEM images revealed that bentonite powder has a compacted interlayer order of heterogeneous surface morphology.
The resulting bentonite HFC membrane surface morphologies were examined by scanning electron microscopy SEM , and the structures exhibit asymmetric structure, which was composed of sponge-like and finger-like structures. Due to, its superhydrophilic property and pore size; the membrane contact angle and water flux performance were obtained at 1. Overall, the results suggest that bentonite can be used in the fabrication of ceramic-based hollow fiber membrane and in addition, can as well be utilized in microfiltration for wastewater treatment.

As such, mining companies are in a search for cheaper, brine free, effective and efficient mine water treatment technology. This study assessed the potential of applying mechanochemically modified cryptocrystalline magnesite-bentonite clay composite for acid mine drainage AMD treatment. To accomplish this, neutralization of acidity and removal of inorganic contaminants from mine effluents were studied using batch laboratory experiments and precipitation of chemical species was determined using pH Redox Equilibrium in C language PHREEQC geochemical modelling.
The present study was divided into three parts which includes: 1 the application of magnesite for remediation of AMD, 2 the application of ball milled bentonite clay for remediation of AMD and 3 the application of magnesite-bentonite clay composite for remediation of AMD. Description: A thesis submitted to the Department of Ecology and Resource Management, University of Venda, in fulfilment of the requirements for the degree of Doctor of Philosophy.

Mainly compacted clayey soils are used as an engineered barrier. Recently, composite materials have gained popularity as landfill liner materials, including the use of waste materials amended with low permeable soils. Though, studies on the composite optimum mix and its corresponding thickness are very scarce.

The aim of this work was to compare the influence of organocations with different length of alkylammonium chain on the structural stability of clays towards mechanochemical treatment. The products were investigated by X-ray diffraction analysis, thermal analysis, scanning electron microscopy and energy dispersive X-ray analysis.
The long-chain organic cations apparently enhance the structural stability of bentonite during high-energy grinding. Sign in Sign up. Advanced Search Help.

Mateusz Stachowicz 2. Pro-ecological technologies. Successful casting demands that during pouring of the foundry mould with molten metal the mould cavity suffers no deformation. This, in turn, demands the use of binding materials that can give the base sand adequate strength.
The main bonding materials are clay binders.
Removal of Heavy Metals Using Bentonite Clay and Inorganic Coagulants
The invention belongs to the production method of cat litter, particularly the production method of a kind of broken bentonite clay particle cat. Along with the raising of people’s living standard, life interest and hobby also constantly increase, and in city, the pet such as cat and dog got more and more in the last few years, and the ight soil of pet is to environment, and people are very dislikes.
Cat litter is exactly a kind of product of process pet dung, and cat litter product was without definite shape in the past, and intensity is low, and dust is large, and antibiotic property is undesirable, and eliminate the unusual smell difference, is not easy to cleaning. The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of cat litter particle balling preparation shape, intensity is high, and dust is little, and antibiotic property is good, eliminates the unusual smell, and is convenient to the production method of the broken bentonite clay particle cat litter cleared up.
The technical scheme that technical solution problem of the present invention adopts is: a kind of production method of broken bentonite clay particle cat litter, comprises by bentonite parts, 20 parts, sodium carbonate, tapioca 10 parts, antibacterial agent 10 parts, waterglass 40 parts and parts, water; It is characterized in that the production method of broken bentonite clay particle cat litter is:.
study to date has demonstrated the effectiveness of bentonite treatment at the field both for clean (i.e. untreated) sand and for sand treated with bentonite.
The main objective of this study was to remove heavy metals such as Cu, Co, Zn, Pb, As, Cd and Cr from industrial wastewater by adsorption using local bentonite clay and roasted date pits. The concentration level of various heavy metals in the industrial wastewater of Riyadh City was above the permissible recommended limits. Also, the concentration level of hazardous heavy metals in the treated water was within the permissible limits for crop production.
The study showed good potential for removing heavy metal ions from industrial wastewater by adsorption using local bentonite clay and roasted date pits. Recent industrial revolution in Saudi Arabia has enormously increased the industrial wastewater production which is highly contaminated with various types of heavy metals. Heavy metal contamination exists in waste effluents of different factories such as metal plating, mining operations, tanneries, chloralkali, ceramic painting, manufacturing paints, catalysts, alloy industries, wire conducting, galvanizing iron, polymer stabilizer, storage batteries manufacturing, semiconductors, pesticides, wood preservation and pigments factories Kadirvelu, ; Brezonik, ; Patterson and Passino, ; Pescod, Heavy metals have been acknowledged as potential health and environmentally hazardous materials.
Many studies have shown that these metals are toxic even at low concentrations. The presence of these toxic metals can cause, in turn, accumulative poisoning, destroy liver, cancer and brain damage when found above the tolerance level Pescod, ; Abdulkarim and Abu-Al-Rub, Meena et al. The adsorption isotherm studies clearly indicated that the adsorptive behavior of metal ions on carbon aerogel satisfies not only the Langmuir assumptions but also the Freundlich assumptions, i.
They should wash the affected area with lukewarm water, dry it with a clean cotton towel, spread the cream on the affected area so as it covers one centimeter over the lesions and then diaper the baby. They should repeat this work every hours, after changing the diapers. Then the process and the effect of treatment will be followed up daily by phone. Needed time for each sample is 6 days. The infant will be observed by the researcher and the physician every other day up to 3 time.

They are regarded as serious wastewater contaminants with detrimental effect to human and environment. Their removal from wastewater poses a serious challenge as they require cost-effective reagent and treatment technique. Three different sets of experiments employing mixing, shaking and no mixing were conducted using a jar test and a shaker with 1. The experiments were conducted without pH adjustment. The results show that a combination of bentonite clay and FeCl3 exhibits a better turbidity removal efficiency compared to the samples with bentonite clay, FeCl3 and AlCl3 respectively.
The variation of the turbidity removal in the samples with mixing shaking and without mixing is insignificant, showing that destabilization-hydrolysis depends upon the strength of the reagent and the physicochemical properties of the solution.
