研究了累托石负载壳聚糖制复合颗粒吸附材料的工艺条件、再生方法,并用其处理含Cu^2＋工业废水。试验结果表明：壳聚糖与累托石质量比为0.09∶1,乙酸浓度为5%,液固质量比为1∶1,制成的颗粒材料吸附效果好。在未调节该废水pH值的条件下,复合颗粒吸附材料用量为0.025 g/mL,反应时间为90 min,温度为40℃,Cu^2＋的去除率为93.96%,处理后的废水中Cu^2＋的残留浓度远低于国家《污水综合排放标准》（GB8978—1996）一级标准。吸附遵循吸附等温式logQe=0.7077logCe-0.4033。复合颗粒吸附材料的吸附效果优于壳聚糖、累托石。用1 mol/L NaCl溶液对吸附饱和复合颗粒吸附材料进行再生,用其处理该废水效果仍然...

In this paper, the preparation technological conditions and regeneration method of a novel granulated adsorbing material of rectorite-supported chitosan and the treatment of Cu2+-containing industry wastewater has been researched. The experimental results show that under the conditions with the mass ratio of chitosan and rectorite of 0.09:1, the concentration of acetic acid of 5%, and the mass ratio of liquid and solid of 1:1, the efficiency of removal Cu2+ with granulated materials is the best. Under the conditions of natural pH, and with the ...
