Natural adsorbents for removal of hexavalent chromium from wastewater: a review

The existence of Heavy metals in water is the sole issue these days. Environmental and Ecological imbalance can be utilised. The high range collection of heavy metals in water and polluted water have negative results on living organisms and the environment. In all the heavy metals like Pb2+, Zn2+, Cr6+etc. Chromium has the most damaging effects on living organisms including plants or animals. It is produced from electroplating and tannery industries. Chromium pollutes the earth and groundwater. The contact of mankind to an extreme quantity of chromium straightly cause respiratory disorders and injures the lungs. Cause of industrialization the chromium pollution in the aqueous solution and wastewater is crossing the tolerance limits of forbearance. Different techniques are utilised for the removal of chromium from the water. Adsorption is a very economical method largely utilised to get rid of heavy metals from commercial and industrial wastewater. It has been examined that this technique is the most functional and commercially workable technique for eliminating heavy metals, specifically chromium. The existing article explains numerous minds of natural waste adsorbents that are observed to be productive in eliminating hexavalent chromium (Cr6+) from factories elimination.
