“…However, they often require extensive sample preparation and separation procedures, owing to the complexity of the sample matrices and the low content of 2,4-D. Also, they are still involved in some problems such as complicated instruments, high cost, time-consuming process, and particularly low selectivity. Therefore, molecularly imprinted polymers (MIPs) with desired selectivity, physical robustness, thermal stability, as well as low cost and easy preparation (Li et al, Contents lists available at ScienceDirect 2011), are gaining popularity in sample pretreatment Liu et al, 2014;Omidi et al, 2014;Yang et al, 2013;Zhong et al, 2014;Zhou et al, 2015) and sensors (Anirudhan and Alexander, 2014;Guan et al, 2011;Wang et al, 2013Wang et al, , 2015 for determination of trace 2,4-D in complex matrices.…”
