Abstract: Objective Two kinds of chlorpyrifos imprinted polymers were prepared to specifically recognize residual chlorpyrifos in crop samples. The recognition mechanism was studied as well. Methods Two kinds of chlorpyrifos imprinted polymers were synthesized by precipitation polymerization. Spectral method, absorption experiment and Scatchard analysis were employed to evaluate its binding properties. Results The MIPs showed a high affinity to chlorpyrifos. Two kinds of binding sites existed in MIPs. Conclusion The binding ratio of chlorpyrifos to MAA and 2-VP were 1:3 and 1:2, respectively. The two kinds of MIPs couldbe used for the separation and preconcentration of chlorpyrifos in samples.
