Determination of resorcinol on glassy carbon electrode modified by carbon nanotube and its application in wastewater analysis

Abstract about interesting chemistry news articles for adsorptive stripping method for the determination of resorcinol on multi-walled carbon nanotube modified glassy carbon electrode (MWNT-GCE) was developed. Cyclic voltammetry was used in the study of the electrochemical behavior of resorcinol on MWNT-GCE. The sharp peak of resorcinol appeared at 0.6 V (vs. Ag/AgCl) with the differential …

Synthesis and characterization of Fire retarded poly (DAMT -co-acrylonitrile)

Abstract In this paper diethoxy-acrylamide methoxyl thiophosphate (DAMT) was synthesized with the reaction N-hydroxymethyl acrylamide and O, O-diethyl phosphorochloridothioate catalyzed by cuprous chloride in presence of triethylamine, and the flame retarded poly (DAMT-co-acrylonitrile) was obtained though free-radically copolymerized process. The properties of copolymer were estimated by Limiting Oxygen Index (LOI) values and thermogravimetric analysis (TGA). The …

Preparation of MAA/TRIM molecularly imprinted polymers and binding selectivity for ciprofloxacin

Gao Jungang, Liu Zhanli, Liu Pengyan, Jiang Ning (College of Chemistry and Environmental Science, Baoding 071002,China) Received Dec. 10, 2006. Abstract  Molecular imprinted polymers (MIPs) for ciprofloxacin were synthesized using methacrylic acid as a functional monomer and trimethylolpropane trimethacrylate(TRIM) as a cross-linker. The binding property and recognition selectivity were studied by equilibrium binding test. The …

Simultaneous determination of ciprofloxacin, ofloxacin and norfloxacin in pharmaceutical preparations by capillary electrophoresis

Abstract A new method was described for simultaneous determination of ciprofloxacin (CIP), ofloxacin (OFL) and norfloxacin (NOR) by capillary electrophoresis with a diode array detector at 280 nm. The separation conditions were investigated and optimized. A new medium, 30 mM sodium tetraborate buffer solution and 22 mM sodium dodecyl sulphate containing 5% (v/v) methanol (pH …

Determination of Tanshinone IIA in two kinds of Chinese traditional patent medicines by HPLC

Abstract A HPLC method for the determination of Tanshinone IIA in the Dan Qi Pian and Tong Mai Chongji was established. The sample was dissolved in methanol and extracted by ultrasound, then chromatographed on LUNA-C18 column with mobile phase of methanol-water (84:16). The flow rate was set at 0.8mL/min and the detection wavelenghth was of …
