A novel voltammetric method for the direct determination of copper in complex environmental samples.
A novel voltammetry with a modified gold electrode for the direct determination of copper in environmental samples, without any pretreatment, is proposed in this paper. A porous disorganized monolayer was formed on the surface of the gold electrode by the self-assembly of mercaptoacetic acid (MAA), which could selectively permeate small molecules. Subtractive square wave anodic stripping voltam...
متن کاملVoltammetric Determination of Copper Ion in Water Samples Using a Drop Casted Biopolymer
Poly-dopamine, inspired by biopolymers of mussels, is an adhesive catecholamine possessing low cytotoxicity and very good biocompatibility. In the present study, poly-dopamine nanoparticles (PDNP), as a biopolymer, were synthesized and characterized using FTIR spectroscopy, scanning electron microscopy and electrochemical methods. The drop casted PDNPs at the surface of carbon paste electrode (...

We represent an environmentally friendly sample of pre-treatment method, ultrasound assisted emulsification microextraction (USAEME) followed by gas chromatography nitrogen phosphorous detector (GC-NPD), to specify atrazine residues in environmental samples. Some parameters affecting the extraction efficiency such as the type and volume of the extraction solvent, emulsification time and additio...

15 صفحه اولSolvent extraction, spectrophotometric determination of copper (II) from environmental samples using o-methylphenyl thiourea as a novel reagent
A simple and rapid method has been developed for solvent extraction and spectrophotometric determination of copper (II) using o-methylphenyl thiourea (OMPT) as a sensitive reagent. The basis of proposed method is formation of copper (II)-OMPT complex. Copper (II) was extracted with 0.020 mol L-1 OMPT in chloroform from aqueous solution in 0.075 mol L-1 potassium iodate. The absorbance of comple...
