摘　　要：制备了CMC改性纳米Ni/Fe双金属材料,考察CMC-纳米镍/铁双金属材料对水体中对硝基苯酚去除的影响因素。结果表明,该材料对PNP的去除率随镍铁比的升高先增加后下降,最佳镍铁比为0.025;随PNP初始浓度的升高先增加后下降,最佳浓度为30 mg/L。反应受pH影响较大,PNP去除率酸性>中性>碱性,且在pH为5时,反应120 min去除率可达100%。CMC-Fe/Ni复合材料的红外光谱表明,CMC的官能团的振动吸收峰随Ni/Fe比增加振幅有所减弱,但整体结构相对稳定。CMC-Modified nano-Fe/Ni bimetallic materials were prepared to investigate the influence factors of CMC-nano-Ni-Fe bimetallic materials on the removal of p-nitrophenol from water.The results showed that the PNP removal efficiency of the material first increased and then decreased with the increase of nickel-iron ratio,and the optimal nickel-iron ratio was 0.025.With the increase of the initial concentration of PNP,the concentration first increased and then decreased,and the optimal concentration was 30 mg/L.The reaction is greatly affected by pH,and the removal rate of PNP is acidic>neutral>basic.When the pH is 5,the removal rate of PNP can reach 100%after 120 min of reaction.The infrared spectrum of CMC-Fe/Ni composite shows that the vibration absorption peak of CMC functional group decreases with the increase of Ni/Fe ratio,but the overall structure is relatively stable.
