Two novel magnetic amino-modified hypercrosslinked resins, P30-1 and P30-2, possessing both high specific surface area and high anion-exchange capacity were successfully synthesized via a sequence of polymerization, post-cross-linking reactions, and amination for the simultaneous removal of hydrophilic and hydrophobic aromatic nitro-compounds. The adsorption behaviors of 4-nitrotoluene-2-sulfonic acid (NTS) and 2-nitrotoluene (o-MNT) onto the obtained resins were investigated. The results demonstrated that P30-1 and P30-2 would be promising materials for both hydrophilic and hydrophobic compounds in water treatment processes.
