Determination of trace amounts of copper(II) by using catalytic redox reaction between methylene blue and ascorbic acid.
A sensitive and selective kinetic-spectrophotometric method is proposed for the determination of microg mL(-1) amounts of Cu2+ based on its catalytic effect on the oxidation of L-ascorbic acid by Methylene Blue in a strongly acidic medium. The reaction is monitored spectrophotometrically by measuring the decrease in color intensity of Methylene Blue at 665 nm. The analysis of Cu2+ ion is perfor...
متن کاملRemoval of methylene blue dye aqueous solution using photocatalysis
The nano sized TiO2 and ZnO are the most active photocatalysts. Methylene blue was used as a reference molecule for the photocatalytic degradation. The TiO2 and ZnO can totally remove methylene blue dye. The effect of various process parameters like initial concentration, contact time, dose of catalyst and pH on the extent of removal of dye by photocatalysis in presence o...

متن کاملRemoval of methylene blue from aqueous solutions using modified clay
Introduction: Discharging of industrial colored wastewaters especially into aqueous environments can cause adverse effects on aquatic life due to their toxic natures. In this study, montmorillonite modified by hexadecyltrimethyl ammonium bromide (HDTMA-Mt) was used for the adsorption of methylene blue (MB). Materials and Methods: The influence of surfactant loading rate, contact time, pH, adso...
متن کاملRemoval of methylene blue using biosynthesized silver nanoparticles
In recent decades, the focus of science and industry has been concentrated on production of metalnanoparticles (NPs). In this study, the biosynthesis of silver NPs by using Tragopogon buphthalmoides(Tragopogon b.) plant was investigated. Various effective parameters on the synthesis such as pH, extractvolume, concentration of silver nitrate, temperature and reaction time were ...
