摘要: 采用煅烧水合法,将易溶于水的造纸副产品磺化木质素(LS)固载在层状双金属氢氧化物(LDHs)表面,制备不溶于水的新型的固体吸附剂Mg₂Al-LS-LDH复合材料.利用XRD及IR对该复合材料的结构进行表征,并对其吸附性能进行研究.结果表明,客体LS并没有进入到LDHs层间,而是与LDHs层板表面发生了羟基键合.该材料对Cu²⁺吸附速率快,30 min接近吸附平衡,去除率达92.2%,吸附量达36.88 mg/g;该材料对Cu²⁺吸附的适宜条件为吸附时间6 h,溶液pH=5,吸附剂用量0.0500 g,吸附温度25℃.

Abstract: Using calcination-hydration method, a new type of solid adsorbent Mg₂Al-LS-LDH was prepared through water soluble sulfonated lignin loading on the LDHs surface. The structure of the composites were characterized by XRD and IR, and its adsorption performance was studied. The results showed that the sulfonated lignin didn't enter into the interlayer of LDHs, but bond with the surface hydroxyl of the LDHs. The adsorption rate of copperion was fast and the adsorption rate was 30 min, closing to the adsorption equilibrium, the removal rate was 92.2%, the adsorption capacity reached 36.88 mg/g. In addition, the optimum adsorption conditions were adsorption time 6 h, pH=5, the mass of adsorbent 0.0500 g, adsorption temperature 25℃.
