In this study, adsorption technique was employed for removal Methyl Red dye. Methyl red dye is azobenzenecarboxylic acid which is well known used in paper printing and textile dyeing. Increasing of usage dyes has shown increasing of pollution in water where it give severely effect to human health and aquatic life. The adsorption of Methyl Red dye was carried out using agriculture waste which is coconut (Cococ nucifera) coir to optimize the effect of contact time, initial concentration, adsorbent dosage and pH and determine the efficiency of raw and activated carbon of coconut coir in removing methyl red dye. Batch studies were performed to evaluate the effects of various parameters: (contact time, initial concentration, adsorbent dosage and pH), on adsorption capacity of methyl red dye. The results showed that raw coconut coir removed methyl red at maximum capacity at 40 minutes while activated carbon at 20 minutes. Both the adsorbents have removed the dye at highest capacity was at 20 mg/L and pH 2. While the dosage were different where the raw coconut coir at 0.05 g while activated carbon at 0.1g. Coconut coir activated carbon was found to be more effective than raw coconut coir as adsorbent in removing methyl red dye where it remove 50% until 80% while raw coconut coir only removed about 40% until 60%.
