to day, the activated carbon is being used to treat the industrial and domestic wastewaters. the suitability of activated carbon for treatment of industrial wastewaters can be quickly predicted by consideration of wastewater characteristics. the results of this paper represent a first step in determining suitability of activated carbon for treatment of wastewaters or effluent of treatment plant...

Although the typical antioxidant, N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD), ensures high durability and long lifespan for rubber compounds, it generates a highly toxic quinone in water, causing serious environmental pollution. Herein, as an alternative material of 6PPD, we newly introduce eco-friendly amine-functionalized lignin (AL) to be incorporated rubber, which can provide...

Organic selenium compounds possess numerous biological properties, including antioxidant activity. Yet, the high toxicity of some of them, such as diphenyl diselenide (DPDS), is a limiting factor in their current usage. Accordingly, we tested four novel organic selenium compounds in the non-parasite nematode Caenorhabditis elegans and compared their efficacy to DPDS. The novel organic selenium ...

The new series of Schiff base were synthesized from 7-methyl-2-phenylimidazo[1,2-a]pyridin-3-amine condensed with different substituted aldehydes (4-Hydroxybenzaldehyde, Vanillin, 3-Nitrobenzaldyde, 4Nitrobenzaldehyde)in presence of catalytic quantities of acetic acid. So the structure offers for this synthesis well coincide with the results obtained bydifferent spectroscopic techniques (IR, 1 ...

Ureido-functionalized compounds play an indispensable role in important biochemical processes, as well chemical synthesis and production. Isocyanates, KOCN particular, are the preferred reagents for ureido functionalization of amine-bearing compounds. In this study, we evaluate potential urea a reagent to graft groups onto amines at relatively low temperatures (<100 °C) aqueous media. Urea i...

Small optically active molecules, and more particularly short-chain chiral amines, are key compounds in the chemical industry precursors of various pharmaceuticals. Their chemo-biocatalytic production on a commercial scale is already established, mainly through lipase-catalyzed resolutions leading to ChiPros™ products among others. Nevertheless, their biocatalytic synthesis remains challenging ...
