Abstract
In order to study the removal effect of ozone on TOC and scattered metals in the supernatant of wet zinc refining process,ozone was introduced into the supernatant for 1 hour of aeration.The results showed that the average removal rate of TOC in the supernatant solution was 12.81%.Meanwhile,aeration also has a certain removal effect on In and Se.In addition,a certain concentration of Fe2+was added to the supernatant,and Fe2+was oxidized and Fe3+was hydrolyzed into Fe(OH)3 colloids using ozone.The adsorption effect of Fe(OH)3 colloids was used to remove some scattered metals.The results showed that after aeration,scattered metals such as Tl,Te,Se,In were effectively removed,and there was no significant change in Mn in the system before and after aeration.关键词
