软锰矿烟气脱硫浸出液同步去除铁、铝试验研究
Simultaneously Removing of Iron and Aluminum From Leaching Liquor of Flue Gas Desulfurization With Pyrolusite
摘要
Abstract
A new method which combined diluting solution and neutralization was proposed for simultaneously removing iron and aluminum from leaching solution of flue gas desulfurization with pyrolusite .The influence of dilution ratio of the leaching solution ,addition of manganese carbonate , temperature and addition of hydrogen peroxide on removal of iron and aluminum were investigated and the sediments were analyzed with XRD .The results show that under the conditions of temperature of 90 ℃ ,the leaching solution dilution ratio of 3 .6 ,addition of manganese carbonate of 60 g/L ,addition of hydrogen peroxide of 10 mL/L ,the removal rate of iron can reach 99% ,and the removal rate of aluminum can reach 96% .T he XRD results show that the iron exists mainly as FeOO H and the aluminum exists as Al(OH)3 in the sediment ,which can prove that the main reactions occurred during the program are hydrolysis precipitation of Al3+ and Fe3+ .关键词
