| Abstract: | The condition and method to determine thiocyanate ion by automatic potentiometric titration was studied. The results show that, the selection of silver electrode as indicator electrode, the electrode 217 with double liquid junction as reference, this method has high selectivity in nitric acid medium to titrate thiocyanate ion. When used in electroplating wastewater analysis, the method is simple and fast, which can print out the results in 4 minutes. |
