摘　　要：为有效解决水体抗生素污染问题,光催化降解技术为当今治理污水领域不可或缺的一部分,铁酸镍(NiFe_(2)O_(4))作为一种尖晶石型铁氧体材料,被广泛应用于光催化环境污染治理。通过简单的水热法制备不同铜含量的铜(Cu)复载NiFe_(2)O_(4)光催化材料,在模拟太阳光照射60 min下,以盐酸四环素为目标降解物,测量其降解率。在制备的样品中17%-Cu@NiFe_(2)O_(4)对四环素降解效率最佳,达到了96%,与纯相NiFe_(2)O_(4)相比降解率提升了31%。In order to effectively solve the problem of antibiotic pollution in water,photocatalytic degradation technology is an indispensable part of today's sewage treatment field.Nickel ferrite(NiFe_(2)O_(4)),as a spinel ferrite material,is widely used in photocatalytic environmental pollution control.In this paper,copper(Cu)composite NiFe_(2)O_(4)photocatalytic materials with different copper content were prepared by a simple hydrothermal method.Tetracycline hydrochloride was used as the target degradation material under simulated sunlight irradiation for 60 min,and its degradation rate was measured.In the prepared samples,17%-Cu@NiFe_(2)O_(4)has the best tetracycline degradation efficiency,reaching 96%,and the degradation rate is 31%higher than that of pure phase NiFe_(2)O_(4).
