Determination of Cobalt(ii) by Coplexation With

Synthesized some copolymer derivative of poly (Styrene –alternative- Maleic Anhydride) (SMA) for removal Cobalt (II) ions from aqueous solutions and determination residual cobalt (II) ions by using spectrophotometric method

Chelating resins have been considered to be suitable materials for the recovery of heavy metals in water treatments. A chelating resin based on modified poly(styrene-alt-maleic anhydride) with Melamine was synthesized. This modified resin was further reacted with 1,2-diaminoethan in the presence of ultrasonic irradiation for the preparation of a tridimensional chelating resin on the nanoscale f...

DETERMINATION 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...

Solid phase extraction of trace cobalt (II) in industrial wastewaters by modified nanotube carbon carboxyl and its determination with flame atomic spectroscopy

Applying a simple and selective sample preparation procedure prior to instrumental analysis is the most important and crucial step in an analytical process. Up to now, various sample preparation techniques based on solid phase extraction (SPE) systems have been developed to isolate various types of analytes from different matrices. In the method presented for preconcentration and measurement of...
