| Abstract: | A way of producing hydrochloric acid for electronic use is introduced in this article. It includes evaporation of hydrogen chloride,gas purification,absorption by high-purified water,final purification and etc. The analysis of the obtained final hydrochloric acid product is carried out by ICP-MS and ion exchange chromatography,it shows that the process can remove the ions,such as Fe,Cu,Pb,As,efficiently which are generally existing in the technical hydrochloric acid. |
