The removal of organophosphorus pesticides from water using a new amino-substituted calixarene-based magnetic sporopollenin

This study describes the synthesis, characterization and application of a new amino-substituted p-tert-butylcalix[4]arene-based magnetic sporopollenin, Calix-EPPTMS-MS (4), for the removal of two toxic organophosphorus pesticides, namely chlorpyrifos and diazinon, from contaminated water. The synthe...
