The present study is an investigation of the inhibitory effect of halides ions and the mineral salt potassium

sulphate; and the catalyzing influences of electrolytes; non – electrolytes and the mineral salt mercuric chloride on the thermal decomposition of potassium peroxydisulphate at 70 OC. The study showed that the specific inhibitory effect of halides ions on the thermal decomposition is in the order: F< Cl < Br < I; while the catalyzing influences of electrolytes and non – electrolytes on the decomposition in the order: HCl > KCl > H2SO4 > K2SO4 > Urea. It was also found that potassium sulphate acts as an inhibitor on the thermal decomposition; while mercuric chloride exhibits a catalyzing influence on the decomposition.
