Discharge of colored effluent from textile industries interfere with the photosynthetic activities of aquatic life. A large number of dyes and their metabolites have been reported to be toxic and carcinogenic to humans and other living things. The removal of this color dye from waste effluents becomes environmentally important. The purpose of this research is to investigate how to remove color from textile industrial effluent using modified and unmodified natural rubber latex. Epoxidized rubber latex (ERL) and unmodified rubber latex (URL) were the absorbents used on textile industry effluent. Adsorption experiments were carried out on the adsorbent and adsobate, while varying its contact time between 30 and 180 minutes in 30-minute increments. The acidity of the solution varied from pH of 2 to 12. The effect of the pH showed that adsorption of dyes was pH dependent. Better adsorption was obtained in an acidic medium as compared to an alkaline medium. It was also noticed that adsorption decreased as contact time increased. The kinetics study revealed pseudo 1 st order and 2 nd order and temkin showed that adsorption process took place. The results showed that adsorbents prepared from rubber latex could be good adsorbents for the removal of dye from textile industrial effluent.
