Abstract:A fast and effective analytical method with biomass solid‐phase microextraction sorbent combined with a high‐performance liquid chromatography‐ultraviolet detector was proposed for the determination of benzoylurea (BU) insecticides in tea products. The novel sorbent was prepared by activating and then carbonizing water hyacinth with a fast growth rate and low application value as raw material and showed a high specific surface area and multiple interactions with analytes, such as electrostatic action, hydrogen… Show more
