All experiments were conducted with an initial pollutant concentration of 10–1mg.
WebIn general, according to the literature, five different types of photochemical quantum yields can be discussed ( ref. 16 ): 1. Apparent Integral Quantum Yield (14) 2. True Integral Quantum Yield (15) 3. Apparent Differential Quantum Yield (16) 4. True Differential Quantum Yield (17) 5. Partial Quantum Yield (18) WebDry catalyst added in its upper valence state (ferric, cupric, chromic) produced high initial rates that fell in 1 to 6 hours tomore » Ferric and ferrous eventually resulted in the same rate. Fe was a much stronger catalyst than Mn or Co, but its rate was limited by Fe solubility of about 0.01 mM at pH 5, resulting in an enhancement factor of ...
