Method of Chemical immobilization of Tannin in the bark and its use for removal of heavy metals from water

摘要

The present Invention belongs to the field of Environmental Science. The objective of the present Invention is the immobilization of vegetable Tannins in the Bark of the Tree so that it can be used for the removal of heavy metals from water.The Invention is based on a Chemical method to immobilize tatinos plants in the Bark of trees and to understand the processing of the Bark from the pre Drying, grinding, process via Chemical immobilization of Tannin and its use to remove Heavy Metals I present in natural Waters and Wastewater.It is applicable for the removal of heavy metals in the treatment of Wastewater containing low concentration.
