The rate of photo oxidation process is followed-up under optimum conditions at natural pH of solution, 10-4 M initial concentration of propanil, 0.4 g\/lZnO loading and 20 ml\/min oxygen flow rate. The photodegradation rate measurements were based on chloride ions liberation and the change in conductivity and pH. Kinetic study of photodegradation was found that the reaction is of the first order reaction and found equal to 0.0046, 0.0079 and 0.0086 min-1 for distilled, tap and river waters, respectively. Also the activation energy and quantum yields were calculated. UV-Visible spectrophotometric and PHLC were utilized to identify final species of the reaction products<\/p><div class=\"item abstract\"><div><h3 class=\"label\">How to Cite this paper?<\/h3><div class=\"csl-entry\"><p><strong>APA-7 Style<\/strong><br \/>Dhahir, .A., Muhyedeen, B.R., Nassory, N.S., Numan, S.A.
