Аннотация:This study explores the interaction between 4-(2-pyridylazo)resorcinol (PAR) and lanthanum fluoride (LaF3) nanoparticles in an aqueous environment. The kinetics of PAR sorption were investigated, and the sorption isotherm of PAR at 20°C was obtained. Using the adsorption model of Frumkin–Fowler–Guggenheim, the magnitude of lateral interaction energy among PAR molecules adsorbed on the LaF3 surface and their sorption energy were calculated. Based on the sorption and spectral data, a structure for the grafted layer of PAR molecules on the surface of LaF3 nanoparticles is proposed.
