Toxicity of Disperse Dyes and its Removal from Wastewater Using Various Adsorbents: A Review
Markandeya , S.P. Shukla and D. Mohan

Abstract:
Discharge of colored effluents into surface water bodies pose adverse effects to aquatic ecology and human beings due to mutagenic and carcinogenic effects of dyes responsible for producing color. Disperse dyes cause risk of sensitization and elicitation to the body when colored clothes contact to the body. It can also be regarded as potential allergens to children with suspected contact sensitization. This study enlisted various dyes have been compiled for the adsorption to provide a detailed up summary of available information on a variety of adsorbents such as activated carbon, CFA, orange peel etc. The adsorption capacity of adsorbents are increased by modifying the surface area in various ways and also varying different parameters like as adsorbent dose, adsorbate concentration, agitation speed, temperature, pH, particle size and contact time to minimize various contaminants present in the industrial wastewater. The role of adsorption isotherms and kinetics through various models are the factors influencing the adsorption capacity.
