A simple in situ visual and tristimulus colorimetric method for the determination of trace arsenic in environmental water after collecting arsenic on a test paper impregnated with mercury(II) bromide and rosaniline chloride by its reduction aeration has been developed. The color development on the test paper is based on the formations of AsH(HgBr)2 (yellow) and/or As(HgBr)3 (brownish yellow) by...
Jacoby, Steven C., Edith Gagnon, Luc Caron, John Chang, and Paul Isenring. Inhibition of Na1-K1-2Cl2 cotransport by mercury. Am. J. Physiol. 277 (Cell Physiol. 46): C684–C692, 1999.—Mercury alters the function of proteins by reacting with cysteinyl sulfhydryl (SH2) groups. The inorganic form (Hg21) is toxic to epithelial tissues and interacts with various transport proteins including the Na1 pu...
With global heavy metal contamination increasing, plants that can process heavy metals might provide efficient and ecologically sound approaches to sequestration and removal. Mercuric ion reductase, MerA, converts toxic Hg2+ to the less toxic, relatively inert metallic mercury (Hg0) The bacterial merA sequence is rich in CpG dinucleotides and has a highly skewed codon usage, both of which are p...
activated charcol phase loaded with 2-propylpiperidine-1-carbodithioate (ppcd) were synthesized based on chemical binding and physical adsorption approaches. the stability of a chemically modified ppcd especially in concentrated hydrochloric acid which was then used as a recycling and pre-concentration reagent for further uses of activated charcol immobilized ppcd. the application of this activ...
