Applicability of phenylpiperazine dithiocarbamate in the determination of As(III) in natural water and biological samples by differential pulse anodic stripping voltammetry
An efficient protocol for the selective oxidation of primary alcohols to aldehydes withH5IO6/V2O5 in ionic liquid [bmpy][PF6] has been developed. High yields of the products, mildreaction conditions and simple experimental procedure make this protocol complementary tothe existing methods. The catalyst can be reused for several times without obvious loss of thecatalytic activity.
متن کاملSelective Determination of Trace-Bismuth by Extraction-Differential Pulse Polarography in Non-Aqueous Media
The voltammetric characteristics of bismuth(III)-oxinate in chloroform at the mercury electrode were investigated and a quasi-reversible behavior for Bi(III) oxinate reduction was confirmed. Preceded by the extraction of Bi(III) oxinate in chloroform, differential pulse polarography was developed in the extracts for determination of the trace-bismuth. The linear range of the calibration gra...
متن کاملA multielement masking method using magnesium hydroxide coprecipitation for the selective determination of lead in water samples by differential pulse anodic stripping voltammetry.
We present a new multielement masking method using magnesium hydroxide coprecipitation for the selective determination of Pb by differential pulse anodic stripping voltammetry (DPASV). The recovery of Pb in the masking method was over 95%, while interfering ions (Cd(2+), Co(2+), Cu(2+), Fe(3+), Mn(2+), and Ni(2+)) could be removed at 100% from the analytical sample. A linear regression was obta...
متن کاملDETERMINATION OF ULTRA-TRACE AMOUNTS OF COBALT BY ADSORPTIVE DIFFERENTIAL PULSE VOLTAMMETRY USING ACDA (2-AMINOCYCLOPENTENE- 1-DITHIOCARBOXYLIC ACID)
The present work describes a selective, rapid and sensitive method for the determination of cobalt using the adsorptive differential pulse voltammetry technique. The method is based on the accumulation of Co(II) complex with 2-aminocyclopentene-1-dithiocarboxylic acid on a hanging mercury drop electrode, followed by measurement of the current of the adsorbed complex. The effects of experimental...
