Polarographic Studies on the Kinetics of Cu()-thiocyanate and the Adsorption Wave of Cu()-thiocyanate

摘要

In the presence of hydrogen peroxide, the effects of temperature and pH to the catalytic reaction velocity of cupric-thiocyanate and the quantities of reduction products adsorbed on the D.M.E. have been studied by polarographic method. According to these experiments, the following empirical equation has been derived for the relation among temperature Ti, concentration of hydrogen ion pHj and adsorbed cuprous-thiocyanate in moles/cm2 Zij, and the rate constant log Kij log Kij=(1/Ti){A(pHj)￡?B}￡? C(pHj)￡?DZij=(1/Ti){￥á(pHj)1/2￡?￥a}￡?￥?(pHj)1/2￡?￥?where, A,B,C,D and ￥á,￥a,￥?,￥? are constants. The Calculated values by both equations are well agreed with empirical values within 8% in the error.
