| Abstract: | The BaCl_2 method is a method of directly determining the content of SO in underground water, Which uses alizarin-S as indictator. standard BaCl2 solution as titrant. Compared with other methods like EDTA content method, the BaCl2 method is easy, fast, and has higher accuracy, precision and relativety. fit for water quality analysis in earthquake momtoring. |
