Vanadium(IV) and vanadium(V) can be determined by using differential pulse cathodic stripping voltammetry technique (DPCSV). Cupferron (ammonium N-nitrosophenylhydroxylamine) was used as ligand to form complex compounds with vanadium ions in Britton–Robinson buffer (BRB) solution. At concentration lower than 1.0×10 −6 M, both V(IV) and V(V) cupferron complexes showed a single cathodic peak...
A new simple sensitive differential pulse polarographic (DPP) method was investigated for the determination of acrylamide (AA) directly in a neutral aqueous solution. The AA showed a well-defined and well-resolved peak in pure aqueous LiCl at −1.84V in the potential range from −1.6V to −1.97V at nitrogen pressure of 0.5kgcm −2 . Among the various electrolytes studied, the AA showed good DPP...
A simpler UV–vis spectrophotometric method was investigated for hydroquinone (HQ) determination using KMnO 4 as oxidizing agent for conversion of HQ to p-benzoquinone (BQ) as well as signal enhancer. Various parameters such as analytical wavelength, stability time, temperature, pH, solvent effect and interference of chemicals were checked and parameters optimized by using 1μgml −1 ...
