【摘要】 以活性炭为载体,采用液相还原法制备活性炭/氧化亚铜（AC/Cu₂O）光催化剂,利用傅立叶变换红外光谱仪（IR）、扫描电子显微镜（SEM）、X射线衍射仪（XRD）等对样品进行官能团分析、形貌观察和物相分析。利用该催化剂处理聚乙烯醇（PVA）废水,实验结果表明:在水样初始pH为5、PVA初始浓度75 mg/L、催化剂投加量4 g/L、反应时间50 min时PVA的去除率为90.60%;且水样初始pH对PVA的去除效果影响最显著。更多还原

【Abstract】 Active carbon/cuprous oxide(AC/Cu2 O)photocatalyst was prepared by liquid-phase reduction method with active carbon as the carrier.The functional groups,morphology and phase of the samples were analyzed by Fourier transform infrared spectroscopy(IR),scanning electron microscopy(SEM),X-ray diffraction(XRD).This type of catalyst was further applied in the treatment of polyvinyl alcohol(PVA)wastewater.The results showed that:the removal efficiency of PVA was 90.60% with a initial pH of 5,PVA concentration of75 mg/L,dosage of catalyst of 4 g/L,and a reaction time of 50 min.The removal rate of PVA was the most significant with the initial pH.更多还原
