Due to the carcinogenicity of atrazine, the effective removal of atrazine in water and soil has become the focus of attention. In the paper, the advanced oxidation technology based on sulfate radicals (${\text{S}\text{O}}_4^{·-}$), which the visible light catalysis and nanocatalyst Co₃O₄/g-C₃N₄ synergistically catalyzed to yield ${\text{S}\text{O}}_4^{·-}$, was constructed to efficiently degrade and remove atrazine. The Co₃O₄/g-C₃N₄ was prepared through a simple solvothermal method, and its microstructure and composition were characterized by SEM and XRD. A series of experiments were carried out to degrade atrazine by Co₃O₄/g-C₃N₄ activation of peroxymonosulfate under visible light, which revealed that the degradation efficiency reached to 78.5 percent in 35 min, CO₃²⁻ had a significant inhibitory effect on the degradation of atrazine in coexisting ions of NO₃-, SO₄²⁻, Cl- and CO₃²⁻, the e-, ⋅OH, and ${\text{S}\text{O}}_4^{·-}$ were mainly active species. Combined with density function theory calculations of Co₃O₄/g-C₃N₄, the high-efficiency degradation of atrazine was due to the synergetic enhancement between photocatalysis and Co₃O₄/g-C₃N₄ catalyst in the constructed catalytic system.

由于of去津的致癌性，有效去除水和土壤中的r去津已成为关注的焦点。在本文中，基于硫酸根的先进氧化技术（${\text{小号}\text{Ø}}_4^{·--}$），可见光催化和纳米催化剂Co ₃ O ₄ / gC ₃ N ₄协同催化产生${\text{小号}\text{Ø}}_4^{·--}$，被构造为有效降解和去除阿特拉津。采用简单的溶剂热法制备了Co ₃ O ₄ / gC ₃ N ₄，并用SEM和XRD对其结构和组成进行了表征。进行了一系列实验，在可见光下通过过氧化一硫酸盐的Co ₃ O ₄ / gC ₃ N ₄活化降解阿特拉津，结果表明，在35 min内降解效率达到78.5％，CO ₃ ^2-具有明显的抑制作用。 NO _3-，SO ₄ ²⁻，Cl-和CO共存离子中阿特拉津的降解研究₃ ²⁻，e-，⋅OH和${\text{小号}\text{Ø}}_4^{·--}$主要是活跃物种。结合Co ₃ O ₄ / gC ₃ N _4的密度泛函理论计算，at去津的高效降解是由于光催化与Co ₃ O ₄ / gC ₃ N ₄催化剂在构建的催化体系中的协同增强。
