| Abstract: | The developments of electrochemical analysis and potentiometric titration method were briefly introduced in this article. Potentiometric titration is a new analytical method which combines potentiometric analysis with traditional volumetric method, and it includes four reaction types, namely acid-base titration, precipitation titration, redox titration and complex metric titration. Potentiometric titration has gained wide attention for its easy operation, clear titration terminal point and man power saving. The application of potentiometric titration for the detection of major elements in geological samples were summarized. How potentiometric titration method was used in analyzing the geological samples, including limestone, dolomite, silicate, chrome ore, iron ore, manganese ore, copper ore and water, were described. The application of potentiometric titration will increase with continuous technology development. |
