how to remove iron oxide from kaolin powder

REMOVAL OF IRON AND MANGANESE IONS FROM

In this work, sub micro kaolin powder has been modified to increase its adsorption ability to remove heavy metals from raw water. The removal efficiency of the natural sub - micro - kaolin powder and its acid (sulfuric & acetic acids) modified forms were investigated for the removal of iron and manganese from raw water samples collected from the northern part of Beni-Suef governorate and
