Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 5469-69-2, Name is 3-Amino-6-chloropyridazine, molecular formula is , belongs to pyridazines compound.

Removal of chloridazon pesticide from waters by Fenton and photo-Fenton processes
Chloridazon (CLZ), also named as Pyrazon and classified as organochlorine pesticides, is widely used during sugar beets cultivation. CLZ being a pesticide with high solubility in water is likely to end up in surface and groundwater bodies because of its high mobility in soil. Due to its toxic properties, it may cause serious problems in human health and ecological cycle. In the present study, the removal of CLZ pesticide by Fenton and photo-Fenton processes was investigated. The effects of parameters such as H2O2, Fe(II), initial CLZ concentration, pH, and temperature were studied. It was observed that CLZ completely disappeared within 1 h and 20 min by the Fenton and photo-Fenton process, respectively, under optimal conditions. The optimal conditions for each processes were attained as 7.5 mg/L Fe(II), 50 mg/L H2O2, 40 mg/L initial CLZ, pH, and 20 degrees C for Fenton process, and 5 mg/L Fe2+, 50 mg/L H2O2, 60 mg/L initial CLZ, pH 3 and 20 degrees C for photo-Fenton process. The reaction kinetics of CLZ followed Behnajady-Modirdhahla-Ghanbery kinetic model. Desphenyl CLZ, pyridazine-3,4,5-trione, oxaluric acid, and 5-hydroxyhydantion were identified as CLZ degradation by-products. Accordingly, the degradation pathway was proposed.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 5469-69-2, in my other articles.
