Abstract: | The kinetics of induced decomposition of potassium peroxomonosulphate (PMS) by the phase transfer catalysts (PTC), viz. tetrabutylammonium
chloride TBAC] and tetrabutylphosphonium chloride TBPC] have been investigated. The effect of PMS], PTC], ionic strength
of the medium and temperature on the rate of decomposition of PMS was studied. The rate of decomposition of PMS was monitored
under pseudo-first-order condition at a constant temperature (50 ± 0.1 °C). The rate of decomposition was first order with
respect to PMS for TBAC and half order for TBPC. The order with respect of PTC was found to be unity for TBAC and half order
for TBPC. A suitable kinetic scheme has been proposed to account for the experimental data and its significance is discussed. |
