COMPOSITION COMPRISING ZEROVALENT IRON FOR REMEDIATION OF RICE PADDY SOILS CONTAMINATED WITH HEAVY METALS AND A METHOD USING THE SAME

摘要

It is included that the ingredient in farmland of heavy metal pollution of a Zero-valent Iron (Fe^0) is economically arranged to by using Zero-valent Iron (Fe^0) cost therein to clean soil and is cheap and causes the second pollution problem for cleaning. One ingredient in the farmland for having cleaned contaminated by heavy metals includes a Zero-valent Iron (Fe^0). One specific surface area of Zero-valent Iron (Fe^0) is 0.05-0.1 m^2g^-1. Rice soil of the Zero-valent Iron (Fe^0) by weight based on 100 components by weight is 1-5 components. Heavy metal is cadmium, uranium, chromium, arsenic or lead.
