硫酸酸洗液闭路循环工艺中杂质行为研究

STUDY ON IMPURITY BEHAVIOUR IN THE CLOSED CIRCULATION TECHNOLOGY OF SULPIIURIC ACID PICKLING SOLUTION

主要研究硫酸酸洗液闭路循环及综合利用工艺中，铜、铅、锰、砷等杂质的含量在硫酸亚铁晶体和用液中的分布规律及除杂原理。为闭路循环工艺的确定提供了理论依据。

In the closed circulation technology of smphuric acid pickling solution and its comprehensive utilization,the distribution rules of impurity content such as Cu、Pb、Mn、As in the ferrous sulphate crystaland its Mother solution and the theory of removing impurities are investigated ,which provides the theoretical basis fot the closed circti lation tech n ology。
