Method for extracting ultra high purity alumina from wasterwater
An object of the present invention is to provide a novel method for extracting ultra high purity alumina from wastewater. Wastewater is recycled, filtered, concentrated and pretreated in order to mix with alkali solution and extraction agent PX-17, undergoing 2 times of purification, adding control agent SX-1 and high temperature heat treatment to finally obtain ultra high purity nano-alumina particles which purity reaches as 99.999% and particle size reaches as 20˜200 nm.
