摘要:

为了提高石墨相氮化碳去除亚甲基蓝的性能,以葡萄糖为碳源、醋酸铵为结构导向剂,采用水热法制备了碳/石墨相氮化碳复合材料。利用红外光谱(FT-IR)、X射线衍射(XRD)和扫描电镜(SEM)等手段对复合材料的结构、组成、形貌及其性能进行了表征,并进一步以亚甲基蓝为目标污染物,采用正交实验L9(34)考察了不同因素对复合材料去除亚甲基蓝的影响。实验结果表明:在光照时间为20 h、溶液体系pH为7.00、复合材料投加量为0.15 g、碳与石墨相氮化碳质量比为5∶10条件下,复合材料对亚甲基蓝的去除率可达95.46%,循环5次后仍可达到88.17%。碳掺杂提高了石墨相氮化碳对亚甲基蓝的去除性能,这为印染废水的处理研究提供了借鉴。

Abstract:

To improve the performance of graphite-phase carbon nitride(g-C3N4) for methylene blue removal,glucose was used as carbon source,ammonium acetate was added as structural director,carbon/graphite-phase carbon nitride composites were prepared by hydrothermal method.Moreover,fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD) and scanning electron microscopy(SEM) were used to characterize the structure,composition,morphological characteristics and photocatalytic performance of the obtained composites.In addition,methylene blue was taken as the target pollutant.The effects of different factors on removal rate were investigated by orthogonal experiment L9(34).The results showed that when the conditions were as follows:the light time of 20 h,pH value of 7.00,dosage of carbon/graphite carbon nitride composite of 0.15 g,the mass ratio of carbon to g-C3N4 of 5∶10,the removal rate reached 95.46 %.After five cycles,it could still reach 88.17 %.Carbon doping g-C3N4 improved the methylene blue removal performance of graphite phase carbon nitride,which would provide reference for future research on printing and dyeing wastewater.
