“Tianyuan Cup national junior high school chemistry and experimental ability contest ” is the most authoritative junior high school chemistry contest, Ningxia Hui Autonomous Region Department of education attaches great importance to this, every year will be organized to participate in junior high school students. I was fortunate enough to participate in the chemical competition marking, this article on the issue of reading the first 2l problems analysis. Question 21 original topic: Fenton method commonly used in the treatment of industrial wastewater containing refractory organic matter. Its principle is the use of Fe ~ (2 +) and H_2O_2 reaction can produce pollutants degradation of the active ingredient. This method is now used to degrade organic pollutants p-CP, explore the relevant factors on the degradation
