- Abstract
The article discusses the study of transition metal ions in textile dyeing wastewaters. The study focuses on the differentiation of metal ions before and after treatment process. Materials of the study include the copper and nickel containing reactive dye, chromium containing acid dyes, and wastewater samples. The method of the study involves dissolving dye solutions in deionized water, determining the metal content of wastewater through atomic absorption, and ozonation of aqueous solutions. Results of the study show that copper removal might be affected by the competition of the variety of ions existing in the wastewater.
