| Abstract: | Objective:To study whether we may use the potassium dihydrogen phosphate as electrolyte in the experiments of electrolysis water.Method:Based on the environmental protection,We used the orthogonal experiment to discover the optimum conditions for the potassium dihydrogen phosphate as electrolyte by using the Hoffman electrolyser.Results:The electrolysis showed optimum effect at the concentration of 10% potassium dihydrogen phosphate under the 18V voltage.Conclusion:Our use of potassium dihydrogen phosphate as electrolyte conforms to the green chemistry requirement,showing better electrolysis effect and no pollution,and it may substitute the sulfuric acid and the sodium hydroxide,with better application value. |
