Abstract:

Guaiacol has been used to determine the activity of peroxide enzyme and uranium. In this paper, we lucubrate the reaction between guaiacol and ammonium persulfate and the reaction mechanism in the presence of silver's catalysis and the activator's behaviour. Based on these, we establish a new catalytic kinetic spectrophotometric method for silver determination and the results are satisfactory when applying to determine silver in the offscum of plumbum-zinc mine after extracting zinc.
