Rawtani 1 Chemistry Department, Sarojini Naidu Govt. P.G. Autonomous College, Shivaji Nagar, Bhopal - 462 016 (INDIA) <p style="text-align: justify;">Dyeing and Textile industries are highly water intensive and are the major contributors to water pollution. In Present Paper we have worked on industrial waste minimization through static bioassay experiment on <em>H. fossitis </em>fish. On exposure to different concentration (including LD50 &amp; LD100) of 5-methyl azodye and its Complexes with Cu²⁺ &amp; Co²⁺ metal ions for 30 days, experimental fishes showed considerable variations in the degree of intoxica&shy;tion. Results indicate that through complexation, toxicity of azodyes can be minimized. Apart from complexation lowering of liquor ratio. Process innovation and Optimizing dyeing processes have also been used for waste management of textile industries.</p> <p>&nbsp;</p> https://journalofchemistry.org/paper/861/ Dyeing industries effluents tatic Bioassa
