Application

  • Conveniently synthesis of porous crown-based resin with efficient 90Sr capture from highly acidic wastewater: This study discusses the synthesis of a porous crown-based resin incorporating 4′,4″(5″)-Di-tert-butyldicyclohexano-18-crown-6, which demonstrates efficient capture of 90Sr from highly acidic wastewater. The article details the performance and applications of the resin in nuclear waste management and environmental protection (Y Su, J He, X Liu, S Jia, K Hu, J Yang, T Liu… - Separation and Purification Technology, 2024).
