-Treating NH4-bentonite with diazomethane results in methylation of adsorbed ammonium with the formation of the tetramethylammonium ion. This ion, which can be completely removed through ion exchange, is distinguished in the IR spectrum by a strong band at 1480 cm -1 due to CH3 group bending vibrations. X-ray diffractograms, CEC, and surface area of the clay are not modified by treatment with d...

background: aflatoxin-contaminated feed cause mortality, suppression of the immune system, reduced growth rates and losses in feed efficiency. an experiment was conducted to evaluate the ability of different levels of sodium bentonite (sb), silybummarianum seeds (sms) and their combination for reducing the adverse effects of aflatoxin b1 (afb1) in broiler chicks. materials and methods: 224 male...

An approach to automating the technological process of obtaining bentonite-containing ion-exchange bipolar membranes is considered. The structures automated systems are given, both with use local automation tools, and industrial controllers workstations. advantages disadvantages each described. A two-level control system sensors, actuators, an controller at lower level a workstation upper sugge...

Three experiments (Exp.) were conducted to determine the interactive effects of sodium bentonite (NaB) with the efficacy of monensin (MON) or salinomycin (SAL) in coccidiosis-infected chicks. Male broiler chicks 5 to 14 d of age were used, and each treatment was replicated with eight (Exp. 1) or four (Exp. 2 and 3) pens of five chicks each. In Exp. 1, MON (80 ppm), NaB (0.50%), or MON+NaB were ...

Methylglucoside (MEG) has been used in the water-based mud with fine montmorillonite (MMT) swelling inhibition, but it still has such shortages as large concentration and low thermostability. In this work, carboxymethyl glucoside (CMG) was synthesized with glucose and sodium chloroacetate and used as swelling inhibitor. The inhibition of CMG against clay swelling was investigated by MMT linear ...

This thesis presents experimental work on foam/sand mixtures carried out in the Civil The first chapter deals with basic aspects of soil conditioning agents and their application to tunnelling, and provides an understanding of the fundamentals of foam behaviour. An introduction to the problems encountered in tunnelling is given. A brief study of foams and their properties is presented and the r...

In this paper, scientific research has been conducted on the production of fluoride disinfectants based local raw materials in order to neutralize fluorine-contaminated soils vicinity industrial enterprises. At same time, processes ion binding environmentally safe, biologically active drugs obtained basis various bentonites, humic substances and chemically physically modified bentonites were ca...

Abstract A common design of a high-level radioactive waste (HLW) disposal system consists the canisters emplaced in tunnels or shafts, with space between heat-emitting and surrounding rock filled bentonite-based material. Understanding behavior this barrier, particular effect prolonged heating on its properties, is important to assess barrier’s long-term performance. The objective present study...

A comparison of the immunogenicity of sodium deoxycholate-disrupted lipopolysaccharides from Escherichia coli cell walls revealed that these fragments, which are nonimmunogenic in the rabbit, have some activity in the mouse. This relationship was independent of the route of immunization and sex, but in both species immunogenicity was restored by dilution or dialysis. Adsorption of disrupted lip...
