Chrome tanning is the most popular tanning system in leather industry and the quality of leather is excellently prepared by this method. The tanning process produces leather from the skin and it offers excellent hydrothermal stability, better dyeing characteristics, and softness to the leather.Chromium pollution is a serious issue because of carcinogenic toxicities of the pollutants and low recovery rate of chromium because of the presence of organic, such as protein and fat is commonly found in huge quantities in tannery waste waters. For this reason, the removal and recovery of the chromium content of tannery waste waters is crucial for environmental protection and economic reasons. Removal and recovery of chromium carried out by using low-cost potential adsorbents. For this purpose three types of activated carbon; C1, the waste generated from sugar industry as waste products and the others (C2, C3) are commercial granular activated carbon is used. The adsorption process and extent of adsorption are dependent on the physical and chemical characteristics of the adsorbent, adsorbate and experimental condition. The effect of pH, particle size and different adsorbent on the adsorption are also effected.
