Novel dithiocarbamate (DTC)-modified crosslinked poly(β−cyclodextrin-co-triethylenetetramine) microspheres (DTC-PCDTTM) possessing a particle size distribution of 141 μm with a span value of 0.65 were fabricated and evaluated by Cu²⁺−MO/TB binary-component systems. DTC-PCDTTM shows excellent simultaneous adsorption performance for Cu²⁺ and methyl orange (MO) or thymol blue (TB) at a DTC graft ratio of 0.21; it also exhibits eminent regeneration and recyclability. The adsorption isotherm data of DTC-PCDTTM for Cu²⁺ and MO or TB in Cu²⁺−MO/TB binary-component systems can be described by the Freundlich and Langmuir models, respectively. The adsorption kinetic data of Cu²⁺, MO, and TB by DTC-PCDTTM are related to the pseudo-second-order kinetic model. The adsorption is a process of spontaneous endothermic entropy increment. The coordination, electrostatic attraction, and the host−guest interaction of β−cD moieties with contaminants are the primary mechanisms for Cu²⁺, MO, and TB adsorption. In the Cu²⁺−MO/TB binary-component systems, competitive adsorption is effectively avoided, and Cu²⁺ shows good synergistic effects with MO and TB.

制备了具有141μm粒径分布，跨度值为0.65的新型二硫代氨基甲酸酯（DTC）改性的交联聚（β-环糊精-三亚乙基四胺）微球（DTC-PCDTTM）并通过Cu ²⁺ -MO / TB进行了评估二进制组件系统。DTC-PCDTTM在0.21的DTC接枝率下对Cu ²⁺和甲基橙（MO）或百里酚蓝（TB）表现出优异的同时吸附性能；它还具有出色的再生和可回收性。Cu ²⁺ -MO / TB二元体系中DTC-PCDTTM对Cu ²⁺和MO或TB的吸附等温线数据可以分别用Freundlich和Langmuir模型描述。Cu ²⁺的吸附动力学数据DTC-PCDTTM的，MO和TB与伪二级动力学模型有关。吸附是自发吸热熵增加的过程。β-cD部分与污染物的配位，静电吸引和主客体相互作用是Cu 2 ⁺，MO和TB吸附的主要机理。在Cu ²⁺ -MO / TB二元体系中，有效地避免了竞争性吸附，Cu ²⁺与MO和TB具有良好的协同作用。
