Despite environmental and geochemical interests, Cr and Fe have been left beyond the reach of determinations by ICP-MS due to severe interferences originating from Ar. The applicability of a dynamic r...
专著信息 书名 Speciation of chromium by in-capillary reaction capillary electrophoresis with chemiluminescence detection 语种 英文 撰写或编译 作者 Weiping Yang,Zhujun Zhang,Wei Deng 第一作者单位 出版社 J. Chromatography A. 200...
An on-line technique for the determination of chromium species with atomic absorption spectrometry is described. The method is based on separation and preconcentration of Cr(III) on a microcolumn of i...
The Schiff base octaazamacrocyclic ligands derived from primary diamines and 3,6-dimethyl/diphenyl-4,5-diazaocta-3,5-diene-2,7-dione, and their binuclear complexes [M2LCl4]Cl2 [M = Cr(III), Fe(III), C...
Symmetric tetradentate (L1) and asymmetric pentadentate (L2) macrocyclic ligands that possess 2 dissimilar coordination sites were prepared. One has a 4-coordinate (N4) and the other has a 5-coordinat...
The catalytic effect of chromium(III) and chromium(VI) on the oxidation of sulfanilic acid by hydrogen peroxide was studied. The reaction was followed spectrophotometrically by measuring the absorbanc...
The stoichiometries and stability constants of the chromium(III) complexes of hydroxysalicylic acid ligands (2,x-dihydroxy benzoic acids; 2,x-DHBA, x = 4-6)(H3L) were determined in aqueous solution by...
Critical micelle concentrations and dissociation constants for chromium soaps (myristate, palmitate and stearate) in a mixture of benzene and dimethyl formamide (7:3, vol/vol) were determined by means...
The critical micelle concentration, CMC, degree of dissociation, and dissociation constant of chromium laurate in alcohols (methanol, ethanol, propanol-1, butanol-1 and pentanol-1) were determined usi...
