Investigation kinetic oxidation of PS by K2S2O8 and AgNO3 catalyst

Abstract

In this research oxidation kinetic panceuo.s (P.S) by S2O8<br />-2 at the presence of AgNO3 as<br />catalyst was studied.The method was spectrophotometer following absorption spectrum (P.S) in<br />wave length of 518 nm. After improving the condition such as PH, P.S concentration, K2S2O8<br />concentration, ionic strength, temperature, rate constant, activation energy, constant frequency,<br />order reaction and thermo dynamical values as ΔH#, ΔS#, ΔG# for catalyst and non catalyst were<br />determined.The results show that oxidation rate P.S by means of S2O8<br />-2 would be increased by the<br />addition of AgNO3 and silver ion would function as a positive catalyst in this reaction.
