| Abstract: | The determination method of total aluminium in polyaluminium solution is improved and the comparison between the results of the improved method and the national standard method is made by t-test. Results show that by accurately controlling the concentration and volume of EDTA solution, some steps in GB15892-1995, such as the masking and demaskiag of metal ions and back titration, can be omitted and no significant difference was detected between the results of two methods. |
