In the present work, a new ligandless-ultrasound-assisted emulsification microextraction (LL-USAEME) method was developed for preconcentration trace amounts of nickel as a prior step to its determinat...
A simple, selective and sensitive kinetic method has been developed for the determination of trace amounts of iodide. This method is based on a catalytic effect of iodide on the reaction between Janu...
摘要 A fast and simple method for preconcentration of Ni2+, Cd2+, Pb2+, Zn2+, Cu2+ and Co2+ from natural water samples was developed. The metal ions were complexed with sodium diethyldithiocarbamate (Na...
摘要 Kinetic-catalytic spectrophotometric methods were proposed for the determination of trace amounts of vanadium element as vanadium(IV) and/or V(V) ions. The vanadium(IV) as VO2+ ion and/or vanadium(...
Partial least squares modeling is a powerful multivariate statistical tool applied to extraction-spectrophotometric simultaneous determination of mixtures of barium and strontium. The method is based ...
Two simple, sensitive and accurate spectrophotometric methods have been proposed for the determination of micro amounts of gold (III) using ethopropazine hydrochloride (EPH) and isothipendyl hydrochlo...
