| Abstract: | The SO 2- 4 ion in industrial hydrochloric acid can be detected rapidly and exactly by OnGuard Ag cartridge technology which can overcome the disturbance of high concentration hydrochloric acid on trace SO 2- 4 ion detection and avoid the influence of acid medium,for it can remove the high concentration Cl - ion from synthetic hydrochloric acid.The recycle rate of the method is kept between 95% 110%,and the relative standard deviation within 5%. |
