Spectrophotometry

Drinking water treated with chlorine or chlorine dioxide contains a mixture of different chlorine species. Their identification, especially at low concentrations, is still problematic because of the number of compounds produced, especially when mixtures of chlorine and chlorine dioxide are used. Thi

Adsorption behavior of molybdate and tungstate from water by acid-treated carbon cloth was investigated. The carbon cloth was treated with sulfuric acid and used for the adsorption of molybdate and tungstate from water samples at nearly neutral solutions. The concentration of ions in the solution wa

A novel spectrophotometric assay method using home-made reagents that can be used to determine the chemical oxygen demand (COD) in real wastewater is described. The home-made reagents were used instead of the American Hach reagents. The principle of measurement was based on direct determination of t
