and ethylenediamine were used as inter-layer reagents to prepare epicholorohydrin-dimethylamine cationic polymer/bentonite (EPI-DMA/Bt) with the monomer-insert inter-layer polymerization method.The influence of the amounts of dimethylamine
epichlorohydrin
and ethylenediamine
reaction temperature and reaction time on the performance of EPI-DMA/Bt were investigated. This composite structure was characterized with XRD and specific surface area measurement.The results showed that when the amount of dimethylamine was 3 mmol·g-1
n(epichlorohydrin/dimethylamine)=1∶1 and m[ethylenediamine/(epichlorohydrin + dimethylamine)]=2%
reacting at 65℃ for 3 h
the adsorption efficiency of active jade blue (K-GL) on the EPI-DMA/Bt product was above 90%.
