METHOD OF REMOVING HEAVY METALS FROM AN AQUEOUS SOLUTION USING PRE-TREATED RECYCLED AGGREGATE

摘要

The present invention relates to recycled aggregate is utilized in a kind of aqueous solution for removing removing heavy metals, comprising: the pretreated product recycled aggregate of production process is by utilizing NaOH solution to recycled aggregate; The step of producing adsorbent is by washing pretreated product recycled aggregate; The adsorbent is used in the aqueous solution of absorption heavy metal. Method of the invention can remove mixing, and absorption heavy metal can advantageously serve to the marine sediment of purification of heavy metal pollution by using the recycled aggregate in aqueous solution. ;The 2016 of copyright KIPO submissions
