ADSORPTION OF COLOR FROM A STOCK SOLUTION USING NEEM LEAVES POWDER AS A LOW-COST ADSORBENT

The regular commercial activated carbon is expensive, so there is a need of alternatives for such application. In present study Neem leaves powder activated using chemical treatment as a low-cost adsorbent. And experiment has done with different weight of adsorbent. The potential of Neem leaves powder adsorbent to remove color impurities from industrial effluent is good. Adsorption isotherm of color solution on adsorbent were determine and correlation with common isotherm equations such as Freundlich Isotherm and Langmuir isotherm model. The maximum removal efficiency was observed up to 80% from prepared Neem leaves at optimum value of parameter. Industrial effluents, dyes from textile industry are common water pollutants and they may be frequently found in trace quantities in industrial waste water so treatment can be done using this adsorbent. Adsorption has been used successfully in the removal of color from effluents. This adsorbent as local replacement for existing commercial adsorbent materials.
