摘　　要：以硼酸和3-氨基1,2,4-三唑为原料,采用固相热解法制备了一种掺硼的氮化碳复合材料,并与过硫酸氢钾活化剂用于可见光催化降解水体中的四环素。利用XRD,SEM,FT-IR等表征分析其晶体结构、微观形貌、化学成分等,分析结果表明成功制备了掺杂硼的C_(3)N_(5)材料,且硼掺杂对C_(3)N_(5)结构有一定的影响。同时分析了催化剂投加量、过硫酸氢钾投加量、四环素的初始浓度、不同质量配比的催化剂等因素对四环素降解效果的影响。实验结果表明:在硼掺杂为2%的C_(3)N_(5),投加量为0.6 g/L,PMS浓度为2 mmol/L时,可见光光照2 h,对四环素的降解率可到达96.78%,其在处理抗生素废水方面具有良好的应用前景。A boron doped carbon nitride composite was prepared by solid-phase pyrolysis using boric acid and 3-amino-1,2,4-triazole as raw materials and was used for visible light catalytic degradation of tetracycline in water with potassium bisulfate activator.Characterization techniques such as X-ray diffraction(XRD),scanning electron microscopy(SEM),and Fourier-transform infrared spectroscopy(FT-IR)were employed to analyze the crystal structure,micro morphology,and chemical composition of the material.The analysis results showed that the boron doped C_(3)N_(5)material was successfully prepared,and the boron doping has a certain effect on the structure of C_(3)N_(5).Additionally,it was analyzed that the effects of various factors on the degradation of tetracycline,including the amount of catalyst added,potassium persulfate dosage,initial concentration of tetracycline and the different mass ratios of the catalyst.The experimental results show that when the boron doping level is 2%C_(3)N_(5),with a dosage of 0.6 g/L,and the PMS concentration of 2 mmol/L,the degradation rate of tetracycline can reach 96.78%under visible light for 2 h,which has a good application prospect in the treatment of antibiotic wastewater.
