Abstract

p-tert-butylcalix[6]arene (CalixSMO) was synthesized for Sr²⁺ separation and the chemical structure of the synthesized product was confirmed by FT-IR, ¹HNMR and MS. The results show that when the initial concentration of nitric acid is 3 mol×L^-1 and CH₂Cl₂ is used as the organic solvent, the Sr²⁺ extraction rate could reach to 60% after extraction for 120 min under 298 K. The ratio of CalixSMO/Sr²⁺ in the inclusion complexes is 1/2. Moreover, studies on the extraction of K⁺, Sb³⁺, Ca²⁺, Sm³⁺, Sn⁴⁺ and Na⁺ show that CalixSMO has good selectivity for Sr²⁺.
