| Abstract: | Use Spectrophotometry to determine the cyanide in water, joins ration of zinc chloride when preparing potassium cyanide standard reserving solution. After one year of experimental study,The result indicates the method can effectively resolve the problem that potassium cyanide standard reserving solution can not be preserved for long-term.At the same time, through recovery rates experiment of standard substance and the examination for national standards sample, It does not affect the result of determination. |
