MANUFACTURING METHOD OF (POLYSTYRENE-DIVINYLBENZENE)-2(2-THIAZOLYLAZO)-P-CRESOL WHICH IS USEFUL FOR ADSORPTION OF METAL ION

摘要

PURPOSE: Provided is a manufacturing method of (polystyrene-divinylbenzene)-2(2-thiazolylazo)-p-cresol of formula (1) absorbing metal ion, specially uranium ion, and working as a ligand of metal for forming chelate with metal to isolate the metal. CONSTITUTION: A manufacturing method of (polystyrene-divinylbenzene)-2(2-thiazolylazo)-p-cresol comprises the following steps of: (1) nitration of polystyrene-divinylbenzene; (2) amination of nitrated polystyrene-divinylbenzene; (3) diazotization of aminated polystyrene-divinylbenzene; (4) reaction of diazotizated polystyrene-divinylbenzene with thiazolylazo-p-cresol.
