Paper Title:
Study on Competitive Sorption Capacity of Sr2+/Cs+ in Zeolite and Palygorskite
  Abstract

Competitive sorption capacity of equal concentration of Cs+ and Sr2+ in zeolite and palygorskite were studied by the intermittence method. zeolite and palygorskite of adsorbed Cs+ and Sr2+ were analysed with the XRD. They could offer some references for the sake of valuing mid-lower radwaste disposition. The results showed that adsorptive equilibrium time of NF to Cs+ and Sr2+ was about seven day, that of ZF was about three day, and that of CA was about fourteen day. Equilibrium adsorptive quantity of ZF to Cs+ and Sr2+ was the best, and that of NF was second, and that of CA was third. Sorption capacity of NF to Cs+ was the better than that to Sr2+, and selection of CA to Cs+ and Sr2+ was the little, and that of ZF was the lest. Equilibrium adsorptive rate of ZF to Sr2+ was almost the 100% and that of ZF to Cs+ was about 71.8% and that of NF to Cs+ was 66% and that of NF to Sr2+ was only 15% and that of CA to Sr2+ was about 28.6% and that of CA to Cs+ was only 16.4%. Crystal unit cell cubage and parameter a of zeolite and palygorskite adsorbed Cs+ and Sr2+ decreased and change of crystal unit cell parameter a、b and β of zeolite and palygorskite were ruleless.
