The influence of phosphates on the decomposition of ozone in water: Chain process inhibition

Russian Journal of Physical Chemistry (Impact Factor: 0.49). 01/2010; 84(7):1136-1140. DOI: 10.1134/S0036024410070101

ABSTRACT The addition of phosphates was found to decrease the rate of the decomposition of ozone in water; they accepted hydroxyl radicals
and thereby inhibited chain ozone decomposition. The presence of phosphates decreased the order of the reaction from second
for pure water to one-and-a-half. The rate constants for ozone decomposition in the presence of various phosphate concentrations
increased as pH grew from 4 to 9.
