Removal of Heavy Metals from Waste Water by using Various Adsorbents- A Review


Objectives: To explore maximum adsorption efficiency towards Removal of commonly occurring Heavy metals from waste water by using various Adsorbents. Methods/Statistical Analysis: In this review paper, we have compiled scattered available research work related to use of various adsorbents for the removal of commonly occurring heavy metals present in effluent and have calculated adsorption efficiency of all the adsorbents used by different researchers just to find out the best and most efficient adsorbent for the removal of particular metal. Findings: It has been found that maximum adsorption efficiency for the Zinc metal is obtained by using Cassava waste (55.9% removed), Cadmium by using Smectite Clay particle (97%), Lead by using Dried water Hyacinth stems and leaves (90%), Copper and Nickel by using Sugar Baggase (94.2% & 87%) respectively. Application/Improvements: This paper would be helpful for anybody to find the best and the most efficient adsorbent for the removal of a particular heavy metal present in the effluent.
