Kinetic features of ammonium persulfate . - SpringerLink

Sep 20, 2016· Abstract. Decomposition of ammonium persulfate in an aqueous medium (353–368 K) is limited by decomposition of persulfate ions with a rate constant logk 2 = (15±3)–(52±8)•10 3 J mol –1 /(2.3RT).The apparent rate constant for decomposition of persulfate ammonium k app = = k 2 γ depends on the decomposition rate constant and the activity coefficient of persulfate ions, the …

It's generally applied in the form of ferrous sulfate (FeSO4) and ferrous chloride (FeCl2). To effectively activate persulfate 100 to 250 mg/L of iron is generally required. Excessive ferrous iron (greater than 750 mg/L) can result in the rapid decomposition of persulfate and therefore a loss in oxidation performance.
