2,4-Dichlorophenoxyacetic acid (2,4-D) is a common pesticide, which is often detected in groundwater and surface water. Half of the benzyl chloride in chloromethylpolystyrene was formed the hypercrosslinked pore structure, while the other half was functionalized by 3-aminopyridine to tailor the macroporous structure. This double pore structure adsorbent (JX-02) was fabricated to investigate its adsorption performance for 2,4-D. The micropore area of JX-02 accounted for 54.04%. At pH 2.97 (without pH adjustment) and 298 K, the maximum adsorpti...
