Efficient bio adsorbents for removal of heavy metals from water: A review
Author(s): Sonia Bharat and Divya Manchanda
Abstract: Due to globalisation water quality is decreasing day by day. Water get contaminated due to number of factors, among these heavy metals are the biggest problem whose major sources are various type of industries like electroplating, tanning, refinery etc. Heavy metal contamination in water lead to severe diseases in human beings. So, it is the need of an hour to purify the water to make it fit for the consumption. A number of physical, chemical, biological methods are reported for purification of water but all have some sort of disadvantages like disposal problem, expensive, not ecofriendly etc. Bio sorption technique has overcome all these issues and come up with 45-96% results. Fruit and vegetable peels are employed as bio adsorbents and work efficiently in this technique. These bio adsorbents are very cheap, easy and safer to use. However, there is a need for extending this laboratory scale work to pilot plant scale so that the costly bio adsorbents can be replaced with these low cost bio adsorbents.
