2026-09-18 Article“Transformation of Atrazine on δ-MnO2 surfaces under dry conditions: Hydrolysis and dealkylation”(new) doi:10.57760/sciencedb.iga.001gp en This thesis mainly focuses on the transformation behavior of atrazine (ATZ) on the surface of δ-MnO2 under dry conditions, as well as its hydrolysis and dealkylation mechanisms. The data content includes the degradation of ATZ under different reaction times, the generation and changes of main and secondary products, the conversion efficiency under different relative humidity and coexisting ion conditions, the comparison of ATZ conversion effects among different crystal forms of MnO2, the removal effect of ATZ in soil after adding δ-MnO2, and the related mechanism analysis results. The data cover various types of experiments and characterization data such as HPLC, UPLC-QQQ-MS, LC-Q-TOF-MS/MS, FTIR and DFT calculations. The data objects include atrazine and other several triazine herbicides, and the environments cover mineral surface dry systems and different types of soil systems. The experimental temperature is mainly 23 ℃, and the relative humidity ranges from 6.40% to 97.30%. This thesis is applicable to the research on the environmental fate of triazine herbicides, the study of non-biological transformation mechanisms on mineral surfaces, the research on soil pollution remediation and control technologies, and the analysis of residual risks of agricultural herbicides. It can provide data references for the study of the transformation laws of atrazine and related pesticides on dry soil and mineral interfaces, and also provide experimental basis for the development and application of technologies to enhance pesticide removal in soil by using manganese oxides.
