Voltammetric 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 (...

15 صفحه اولPreconcentration and Determination of Chromium (III) from Sea Water Samples Using Ion Imprinted Activated Carbon
A simple ion imprinted amino-functionalized sorbent was synthesized by coupling activated carbon with iminodiacetic acid, a functional compound for metal chelating, through cyanoric chloride spacer. The resulting sorbent has been characterized using Fourier transform infrared spectroscopy (FT-IR), elemental analysis, thermogravimetric analysis (TGA) and evaluated for the preconcentration and de...

متن کاملSeparation, Preconcentration and determination of Hg (II) Ion in Water Samples by Cloud Point Extraction Technique Coupled with UV-VIS Spectrophotometry using a New Complexing Agent
In this study a cloud-point extraction process using non-ionic surfactant Triton X-114 for extraction of mercury (II) from aqueous solutions was developed. The method is based on the complex formation of Hg (II) with benzyl (pyridin-2-yl) methylcarbamodithioate at pH 5.5. After preconcentration and dilution of the surfactant-rich phase, the enriched analyte was determined by s...
