Adsorption is used as a potential method for the removal of color (dye) from industrial waste water. In this paper an easily available low cost Belpatra (Aegel marmelos) bark powder was used as an adsorbent for the removal of textile dye Torque Blue. For the present work several experiments were conducted at different adsorbent dosage, pH, temperature, dye concentration, particle size, and contact time in a batch adsorption mode. The experimental results revealed that maximum adsorption capacity of Belpatra bark powder on Torque blue dye was found to be 98% at an adsorbent dosage of 0.7gm in 100 ml dye …

Technical feasibility of natural iron-rich sandy soil as a low-cost adsorbent for removal of lead from water was investigated . The soil, which had an iron content of 3,719 mg/kg, was collected from Hulu Langat, Malaysia, and was used for adsorption studies without any surface modification through chemical treatment. The effects of pH, solution: soil ratio and initial lead concentration on the adsorption efficiency were studied using response surface methodology based on Box–Behnken experimental design. The results showed that pH of the solution had the highest impact on the adsorption efficiency whereby adsorption efficiency of 97% could be achieved at …
