采用FTIR和SEM对纤维素-g-聚丙烯酸/丙烯酰胺/蒙脱土（LNC-g-PAA/AM/MMT）纳米复合高吸水性树脂的结构进行表征。研究亚甲基蓝染料的初始质量浓度、吸附时间、吸附温度和pH等不同条件下，对LNC-g-PAA/AM/MMT吸附该染料吸附量的影响。此外，在最佳条件吸附饱和时，改变解吸时间、HCl浓度等研究LNC-g-PAA/AM/MMT的解吸性能。结果表明：初始质量浓度为2500 mg/L，120 min，30℃，pH=5时，LNC-g-PAA/AM/MMT的吸附量高达2038.7 mg/g。整个过程很好地符合伪二级动力学模型和Langmuir等温线。在解吸时间120 min，HCl浓度0.05 mol/L时，解吸率高达73.16%。

The structure of cellulose-g-p olyacrylic acid/acrylamide/montmorillonite nano-composite super-absorp-tive resin(LNC-g-PAA/AM/MMT) can be characterized by FTIR and SEM. Under different conditions,such as the initial mass concentration,adsorption time,adsorption temperature,pH,etc.,the effect of LNC-g-PAA/AM/MMT adsorption capacity on the adsorption quantity of the dye has been studied. In addition, on the basis of the optimum adsorptive saturation conditions,the desorption capacity of LNC-g-PAA/AM/MMT has been studied by changing the desorption time and HCl concentration. The results show that when the initial mass concentration is 2 500 mg/L ,ad-sorption time 120 min,adsorption temperature 30℃,and pH=5,the adsorption quantity of LNC-g-PAA/AM/MMT is as high as 2 038.7 mg/g. The whole process complies well with pseudo-second-order model and the Langmuir isotherm. When the desorption time is 120 min and HCl concentration 0.05 mol/L ,the highest desorption rate is as high as 73.16%.
