AbstractThe photoreaction behaviour of p-substituted sodium phenylsulphonate in aqueous solution and colloidal system has been studied by means of spin trapping-ESR method. The results indicated that the reaction processes and the intermediate free radicals formed were dependent of the pH values as well as the existence of colloid. The sulfur-centered radicals SO3-., which were the main product were observed, and the carbon-centered radicals and hydrogen radicals were also detected in a certain range of pH values. It was discovered that the primary rate of free radical generation changed with the pH values in an exponential form while pH<4.
