通过取代反应合成了磺酰化β‐环糊精（6‐OTs‐β‐CD），并采用红外光谱与核磁共振对合成材料进行表征，验证了材料合成的可靠性；通过6‐OTs‐β‐CD与N ，N′‐二苯硫脲以2∶1的摩尔比反应合成了包合物6‐OTs‐β‐CD‐N ，N′‐二苯硫脲，采用综合热分析表征了包合物的热稳定性；用可见分光光度法分析了包合物及N ，N′‐二苯硫脲对钍离子的吸附行为。结果表明，室温下，相较于 N ，N′‐二苯硫脲，6‐OTs‐β‐CD‐N ，N′‐二苯硫脲包合物对钍的吸附平衡时间大幅缩短。最佳吸附条件为pH＝4、震荡反应10 min、吸附剂加入量为0.025 g ，在此条件下吸附容量达27.46 mg／g ，吸附率达91.5％。...

6-O-monotosyl-deoxy-β-cyclodextrin (6-OTs-β-CD) was prepared by literature method, and analyzed by IR and 1HNMR. The analytic results show that the goal material is reliable. The inclusion complex was acquired by the reaction of 6-OTs-β-CD and N, N'-diphenyl thiourea with the mole ratio of 2:1, and then the comprehensive thermal analysis spectrum was used to study the thermal stability of inclusion complex. The adsorption behaviors of the inclusion complex and N, N'-diphenyl thiourea to Th4+ were studied with the method of visible spectropho...
