Removal of color from aqueous solution by using low cost adsorbent was conducted by batch experiment. The potential of the low cost adsorbent Azadirecta indica leaves (Neem) to remove Methylene Blue from aqueous solution were assessed at room temperature. Laboratory investigation of the potential of Azadirecta indica leaves (Neem) powder to remove methylene blue dye from aqueous solution has been studied. The effects of various experimental parameters, such as pH (3-11), adsorbent dosage (1-12 g/l), contact time (15-240 min) and initial dye concentration were investigated. The results showed that the dye removal increased with increase in the initial concentration of the dye and also increased in amount of biosolid used and initial pH.
