Efficient Removal of Dyes Using Almond Husk as a Natural Adsorbent

Abstract

Industrialization and urbanization is considered as, one of major threat to pollution of air, soil and water systems. Among these, water pollution is considered as important one. The addition of various pollutants to water resources is considered as major threat for deterioration of water quality and makes it unsuitable for domestic purposes. Out of many water pollutants, dyes are considered as most hazardous for the plants, animals and human beings. So, it is very important to conserve water due to limited availability. In the present study, almond husk was neutraceutical spent used as adsorbent for the removal of dyes from aqueous solutions in batch mode experiments. Parameters like contact time, pH, adsorbent concentration, adsorbent dose were studied. The results show that, almond husk is a very good adsorbent for the removal of dyes from the aqueous medium. The adsorption isotherms like Freudlich and Langmuir model were calculated and found to be favorable.
