Oxygen → Potassium Persulfate

Comparative Example A was prepared as for the “Conventional Complete Solution” described in Table 2 of Example 1 of U.S. Pat. No. 6,818,142. A 11.2% potassium monopersulfate solution was prepared by dissolving OXONE (12.6 g) potassium monopersulfate in deionized water (100 g) at a temperature of 22° C. The OXONE was mixed until completely dissolved. The resulting solution produced was prepared below the saturation limit expressed in Table 1 above. The resulting solution contained 0.51% active oxygen, 5.00% KHSO5, 2.54% KHSO4, pH=1.2, 10.56% total dissolved solids (TDS), and a 0.15:1 weight ratio of AO/SO4. A rate constant was derived from the data in Table 2 of U.S. Pat. No. 6,818,142 and found to be k=0.0062. Using Equation 1 above, the value of t10% was 17 days, where t10% is the time it takes to loose 10% of the active oxygen.
