Abstract

Dyes entering wastewaters affect both the aquatic creatures and humankind because they are toxic while also carcinogenic. As this is a trouble-free yet effective process, the adsorption system technology is being extensively employed to remove colours all from aqueous solutions for years. We investigated the use of Erythrina indica (EI) leaf powder, bark powder, leaf ash and bark ash for the adsorption of methyl red dye (MRD) from aqueous samples for its first time. The %MRD clearance using EI leaf powder, EI leaf ash, EI bark powder and EI bark ash displayed that the optimal condition of MRD clearance happened at pH unit of 4, 100 ppm concentration of MRD, sorbent dose at 1.4 gm/l, 27 oC temperature, and mechanical shaker agitation speed of 100 rpm. The best equilibration times for greatest percentile MRD removal were 105 minutes with EI leaf powder, EI leaf ash, EI bark powder and EI bark ash. The leaf and bark powder of EI and leaf and bark ash of EI can be considered an alternative feedstock in eliminating MRD in aqueous system because of its strong biosorption capacity and low cost, according to this study.
