Abstract :

In this research oxidation kinetic panceuo.s (P.S) by S2O8-2 at the presence of AgNO3 ascatalyst was studied.The method was spectrophotometer following absorption spectrum (P.S) inwave length of 518 nm. After improving the condition such as PH, P.S concentration, K2S2O8concentration, ionic strength, temperature, rate constant, activation energy, constant frequency,order reaction and thermo dynamical values as ΔH#, ΔS#, ΔG# for catalyst and non catalyst weredetermined.The results show that oxidation rate P.S by means of S2O8-2 would be increased by theaddition of AgNO3 and silver ion would function as a positive catalyst in this reaction.
