Abstract
Sorption of organic reagents Arsenazo III and 1-(2-pyridylazo)-2-naphthol onto optically transparent mesoporous polymers prepared from macroinitiators and toluene 2,4-diisocyanate was studied. The possibility of preconcentration of organic reagents and their complexation with Cu(II) and Ca(II) ions in the polymer pore voids was demonstrated. Experiments on spectrophotometric analysis using the polymeric support showed that the lower limit of determination was 20 μg mL−1 for Ca(II) and 2 μg mL−1 for Cu(II).
