Resins containing alpha-hydroxyphosphonic acid groups used for adsorption of dyes from wastewater
The synthesis of styrene-divinylbenzene copolymers functionalized with alpha-hydroxyphosphonic acid groups is presented. The phosphorus content was determined in order to calculate the degree of functionalization with pendant alpha-hydroxyphosphonic group, with values of 0.66 for St-1%DVBHOPHOS and 3.14 for St-6.7%DVBHOPHOS. Their characterization by IR, thermogravimetry is reported. The kinetics of adsorption of three dyes on St-6.7%DVBHOPHOS polymer was studied.
