To reduce the shortcomings of existing filtering assistance, talc was modified by a two-step method. In first step, talcum powder heated microwave in acid solution. second stirred with Hexadecyl Trimethyl Ammonium Bromide (HTAB) solution for optimum time under an temperature. The temperature, and amount HTAB were investigated batch membrane filtration experiments kaolin suspension. effects new ...

In this research, the interaction of hexadecyl trimahyl ammonium bromide (HTAB) with enzyme ureasehas been investigated comprehensively at different experimental conditions such as ionic strength, proteinconcentration using ion selective membrane electrode of surfactants. The obtained binding isotherms frompotentiometnc studies have been analyzed by different theories such as Wyman binding pote...

A new chitinase isozyme (Chitinase A), which had only one optimum pH toward a long substrate, glycolchitin, was purified from the peel of yam tuber by CTAB (hexadecyl trimethyl ammonium bromide) treatment and ammonium sulfate fractionation, followed by column chromatography on DEAE-Cellulofine A-500, chromatofocusing, and gel filtration on Sephacryl S-100. The molecular weight was 28,000 by SDS...

quaternary ammonium compounds (qacs) are employed both as disinfectants for manual processing lines and surfaces in the food industry, and in human medicine area. qacs also cause cell death by protein denaturation . one of the qac is cetyl trimethyl ammonium bromide (ctab) that appears to rapture the cell membrane. the primary site of action of ctab has been suggested to be the lipid components...

Precious metals are currently associated with selenium (naumannite, Ag2Se) and tellurium (calaverite, AuTe2; sylvanite, (Au,Ag)2Te4) to form species refractory to cyanidation. The aim of this preliminary work was to study the use of the solvent extraction technique to recover tellurium and selenium ions from a synthetic solution similar to the cyanidation effluents to recycle the free cyanide b...

poly(styrene-co-butyl acrylate)/clay nanocomposites were synthesized via in situ atom transfer radical polymerization using activators generated by electron transfer in the presence of a montmorillonite ion-exchanged with mixed surfactants of dodecyl trimethyl ammonium bromide and vinyl trimethyl ammonium chloride. the living nature of polymerization is confrmed by occurrence of narrow molecula...

Two-dimensional MXenes are generally prepared by the etching of acid solutions. The as-synthesized terminated group anions (F–, Cl–, et al.), which affect electrochemical performance MXenes. Here, we report a novel method to prepare Mo2C MXene from Mo2Ga2C hydrothermal alkali Highly pure was successfully synthesized NaOH, while etchings LiO...

Iron-based oxide catalysts for the NH3–SCR (selective catalytic reduction of NOx by NH3) reaction have gained attention due to their high activity and structural adjustability. In this work, iron–niobium, iron–titanate iron–molybdenum composite oxides were synthesized a co-precipitation method with or without assistance hexadecyl trimethyl ammonium bromide (CTAB). The CTAB (FeM0.3Ox-C, M = Nb, ...
