摘 要:正Ion-imprinted polymers (ⅡPs) are similar to molecular imprinting polymers (MIPs),but they can recognize metal ions after imprinting and retain all the virtues of MIPs.A particularly promising application of ⅡPs is the solid-phase extraction preconcentration of analytes present in low concentration or the separation of the analytes from other coexisting ions or complex matrix [1~2].In this paper,dysprosium (Ⅲ) imprinted thenoyltrifluoroacetone (TTA) modified silica gel sorbent was synthesized by surface
