Abstract
Negatively charged copper(II) and zinc(II) chelates with 5,10,15,20-tetrakis(4-carboxyphenyl)-21H,23H-porphine were incorporated into the precipitates formed from the aqueous solutions of thermo-responsive polymer; poly(Nisopropylacrylamide). In the presence of an appropriate kind and amount of quaternary ammonium ion, the recovery of the chelate was quantitatively. Sub-ppt level zinc(II) in water by the photometric detection in HPLC was successfully achieved, because of the highly efficient concentration.
