Comparison of Adsorption of Malachite Green on to Low-Cost Adsorbents - A Review

The adsorption of malachite green onto Borassus bark and Juliflora bark was studied under various conditions such as concentration of adsorbate, adsorbent dosage, effect of the contact time, adsorbent dosage solution of pH were studied in batch experiment at 300C. It was rapid, stable and occurs in less than 60 minutes. Results showed that a PH of 7 is favourable for the adsorption dye. The objectives of this work were to compare the process of adsorption of malachite green with two types of absorbents (Borassus bark and Juliflora bark) and the isothermal data could be well described by the Freundlich. Results showed that Borassus bark and Juliflora bark are suitable for the adsorption of malachite green and could be used as a low cost effective adsorbent in the treatment of the industrial wastewater.
