A novel composite matrix polymethacrylic acid-grafted Chitosan/Bentonite (PMAA-g-CS/B) was prepared through graft copolymerization reaction of methacrylic acid and chitosan in the presence of bentonite and N,N’methylene-bisacrylamide as cross linker. The composite was well characterized using FTIR, XPS, SEM, TG/DTG, surface area analyzer and potentiometric titrations. The adsorption behavior of...

Samples of bentonite layers from altered volcanic ash layers of the Anthering Formation in Salzburg, Austria, which most likely covers the Paleocene/Eocene boundary, were analyzed for their chemical composition. The results of the major and trace element determination confirm the previously suggested appearance from at least two different primary localities. One sample has low abundances in TiO...

Our research material involved Mustela neovison mink feed collected at a farm during two feeding seasons: in preparation for animal reproduction and winter fur coat development. The feed was divided into 3 treatment groups – the control with no bentonite supplement and 2 others with dietary sodium bentonite additive at doses of 1% and 1.5% of weighed feed portion. The material was studied for t...

The objective of this study was to explore the potential use of pulp (by-product) from coffee processing and Na-bentonite (commercial product) for minimizing the environmental risk of Zn, Pb and Cd in soil collected from a former mine and zinc-lead smelter. The effects of soil amendments on the physicochemical properties of soil, the structural and functional diversity of the soil microbiome as...

Refining of edible and cosmetic oil consists various steps which include bleaching process. Bleaching is an important step as it removes colour pigments resulting in improvement taste appearance. In this work, activated bentonite marula shells were used to refine crude oil. Fresh was using H2SO4 whilst both KOH. Vacuum performed the shells. Fresh, activated, spent bentonites analysed X-ray Diff...

Abstract A polymer-enhanced bentonite-sand mixture has been widely used as a clay liner. This research focuses on the potential use of chitosan natural polymer mixed with bentonite liner base material. The is type calcium bentonite, which easily obtained in market. Meanwhile, produced from shrimp shell waste and also available process mixing percentage 2–6% was carried out using certain method,...

The usage of wastes of baggase would be admirable from environmental and solid waste management point of view. Thus, herein, this data set present a facile method for providing an adsorbent from mixture of bagasse-bentonite. The prepared adsorbent was applied to remove Cd2+ from aqueous solution. The characterization data of the adsorbent were analyzed using XRF and FTIR methods. The XRF test r...

Short term in vitro incubations were used to evaluate the effect of fumaric acid bentonite coupled addition on rumen fermentation effeciency. Ruminal contents from five steers were used for preparation of inoculums of mixed rumen microorganisms that were used in generatation of three treatment systems, negative control, fumaric acid treated, and fumaric acid – bentonite coupled treated. The fer...

Spectroscopic analysis was used to study the effect of wine processing on phenolic composition. Various classes of phenolic compomtds were detected and characterized by ultraviolet (UV) and Infrared (IR) spectroscopy in white grapes of Sauvignon Blanc and French Colombard, as well as in wines prepared from these grapes. Comb/ned treatment with bentonite, egg albumin and Polycinr AT decreased th...
