The effect of bentonite fining on the total proteins and the heat-unstable (80°C, 6 h; 4°C, 12 h) proteins in GewLirztraminer, White Riesling, Sauvignon blanc, and Sylvaner wines was investigated. Protein molecular weights (MW), isoelectric points (pl), and glycoproteins were determined by using lithium dodecyl sulfate polyacrylamide gel electrophoresis (LDS PAGE) and two-dimensional isoelectri...

A hydrophobic-bentonite catalyst (cetyltrimethyl ammonium bromide-bentonite) has been used as a very mild, neutral, eco-friendly, reusable, non-toxic, low-cost and easily available catalyst. It was prepared by replacing the exchangeable Na+ cations of a homoionic Na–bentonite with cetyltrimethyl ammonium bromide (CTMAB) cations. The catalyst was characterized by XRD, BET and SEM. The...

The aim of this investigation was to study the relationship between activation factors and adsorption of cationic dye, methylene blue MB, by activated bentonite. The adsorption index was investigated as a function of acid type, time and temperature. A commercial bentonite was selected as a starting material and the effect of heat treatment on MB adsorption were determined in a batch setup. Thou...

a study was conducted to determine the efficacy of esterified glucomannan, sodium bentonite and humic acid, in counteracting the toxic effects of aflatoxin in experimentally contaminated diets (254ppbaf) fed to broiler chickens. 7-day-old male broiler chicks of similar weight were randomly assigned to one of the nine dietary treatments with four replicates of 12 chicks each. chicks were grouped...

Drilling fluids can be considered complex liquids containing several desired materials. These materials (small additives) are specialty products that serve a specific need, such as controlling the rheological properties of drilling fluid and reducing corrosion for operational both oil gas wells. Additives used to resist called inhibitors. Previous research has shown polymers Carboxymethyl Cellu...

The present study reports, the synthesis of ZnO-bentonite nanocomposite by the incorporation of ZnO with bentonite clay. The nanocomposite was characterised by XRD and SEM. ZnO-bentonite was effectively used for removal of Methylene Blue (MB). Removal of MB takes place by photocatalytic degradation and adsorption. Photocatalytic degradation of MB occurs by advanced oxidation process. The factor...

in this study a sample of bentonite obtained from semnan mines, was modified by a surfactant to prepare an organoclay with high surface area. bet analysis showed that the modification increased its surface significantly. the prepared sorbent was used for removal of dyes and other organic pollutants from a waste water obtained from ekbatan textile company. adsorption was studied in various times...
