Reduced graphite oxide (rGO) was synthesized from graphene oxide (GO) by reduction process with the aid of ascorbic acid. GO was synthesized from graphite precursor by modified Hummers method. The prepared materials were characterized in terms of surface morphology, structure, functional group, and elemental compositions by different methods such as SEM/EDS, XRD, FT-IR, Raman, and BET. rGO/K 2 S 2 O 8 system was used to study the impact of different reaction parameters on the degradation of tetracycline in water. The results showed that GO and rGO materials were successfully synthesized, with high purity. The prepared rGO promoted the degradation of tetracycline by sulphate radicals generated from K 2 S 2 O 8 with an efficiency of two-fold higher than sole K 2 S 2 O 8 . More than 95% of 5 mg l −1 tetracycline were removed by rGO/K 2 S 2 O 8 system after 40 min...

rGO /过硫酸盐无金属催化降解四环素：反应参数的影响

在抗坏血酸的帮助下，由氧化石墨烯（GO）通过还原过程合成了还原的氧化石墨（rGO）。GO采用改良的Hummers方法由石墨前驱体合成。通过不同的方法，如SEM / EDS，XRD，FT-IR，拉曼和BET，对制备的材料的表面形态，结构，官能团和元素组成进行了表征。用rGO / K 2 S 2 O 8系统研究了不同反应参数对水中四环素降解的影响。结果表明，GO和rGO材料已成功合成，纯度高。制备的rGO促进了K 2 S 2 O 8产生的硫酸根自由基对四环素的降解，其效率是单一K 2 S 2 O 8的两倍。
