Banana peel; Chromium; Low-cost; Acrylonitrile; Grafting Abstract The adsorptive removal of hexavalent chromium Cr(VI) from aqueous solutions was investigated by acrylonitrile grafted banana peels (GBPs). Banana peels were treated with 10% HCl, followed by alkaline hydrolysis with 10% NaOH, and washed thoroughly. The bleaching of alkali hydrolyzed peels was carried out with sodium chlorate (NaC...

Advancement in thermal three-dimensional printing techniques has greatly increased the possible applications of various materials in medical applications and tissue engineering. Yet, potential toxic effects on primary human cells have been rarely investigated. Therefore, we compared four materials commonly used in thermal printing for bioengineering, namely thermally printed acrylonitrile butad...

Acrylonitrile, an industrial chemical, is a multisite carcinogen in rats and mice, producing tumors four tissues with barrier function, that is, brain, forestomach, Zymbal’s gland, Harderian gland. To assess mechanism(s) of action (MoA) for induction neoplasia to evaluate whether the findings rodents are indicative human hazard, data on potential key effects produced by acrylonitrile rodent tar...

A previous study has shown that acrylonitrile (ACN) has a long half-life in rainbow trout muscle and that [14C]ACN appears to be bound to a 10,000-Da protein in muscle. The labeled protein was purified from muscle of trout exposed to [14C]ACN, separated on 20% SDS-PAGE, and digested for amino acid analysis and sequence analysis. These studies indicated that the labeled protein was the Ca(2+)-bi...

hard magnetic srfe12o19 (srm) nanoparticles were synthesized by a facile sonochemical reaction. the magnetic nanoparticles were then added to acrylonitrile-butadiene-styrene, polystyrene, polycarbonate, and poly sulfone to make magnetic nanocomposites. the magnetic properties of the samples were also investigated using an alternating gradient force magnetometer. the strontium ferrite nanopartic...

Dienes have been formed with good stereoselectivity and in good yield from simple aldehydes and acrylates/acrylonitrile in the presence of a phosphine and a Lewis acid through a modification of the Morita reaction.

This paper presents a review of the methods available for preparing block and graft copolymers in which one component is acrylonitrile. Methods using polymer ions and polymer radicals are considered together with a useful new technique based on reactions of nitrile groups with amide compounds of group IV transition metals. Because of its polarity and its unusual solubility properties, a polyacr...

Styrene is a high production chemical; the production capacity for styrene in the United States was over 12 billion pounds in 2008. Small amounts of styrene are naturally present in foods such as legumes, beef, clams, eggs, nectarines, and spices. It can also be present in packaged foods by migration from polystyrene food containers and packaging materials. Styrene is a combustion product of ci...

The addition of acetonitrile, propionitrile, and acrylonitrile to tetramesityldigermene was investigated and compared to the addition of acetonitrile and acrylonitrile to germanium dimers on the Ge(100)-2×1 surface. In each case, a 1,2,3-azadigermetine was formed as the major product. As on the surface, the addition of nitriles to digermenes was found to be reversible, providing the first examp...
