los摘要：Its speed, safety, and convenience have made the persulfate oxidation method popular in recent years for determining total N and P in natural water, soil solution and soil extracts. However, the compositions of the oxidizing reagent (i.e., the concentrations of K2S2O8 and NaOH in oxidizing reagent) ud by different rearchers varied. In this study, a standard urea solution was ud as a sample to evaluate the oxidation efficiency of the various oxidants. The oxidizing reagent chon was a
lso ud to determine the total nitrogen (N) in 0.5 mol L−1 K2SO4 soil extracts and total phosphorus (P) in pure compound, compared to the traditional digestion method. Results showed that the efficiency of an oxidizing reagent depend not only on the amounts of K2S2O8, but also on the NaOH concentration in the oxidizing reagent. The pH
