In this study, the mol. imprinting polymer (MIP) was prepared using α-naphtholphthalein as a template, 2-(diethylamino)ethyl acrylate as a functional monomer and ethylene glycol dimethacrylate as a crosslinking agent by aid of free radical polymerization onto surfaces of vinyltrimethoxysilane modified silica gel. The MIP was extracted with acetonitrile for overnight to remove the template mol. from the MIP. Non-imprinted polymer (NIMP) was synthesized using the same materials except α-naphtholphthalein as template mol. α-Naphtholphthalein adsorption on surfaces of the both polymer was studied at three different temperatures (19°C, 25°C and 35°C). It was observed that the adsorption capacity increased with increasing temperature and with time. The time required to reach the equilibrium for two polymers and all temperature was accepted to be nearly 6 h. The saturated adsorption amounts at the equilibrium were found as 120 mg/g, 123 mg/g and 127 mg/g at 19°C, 25°C and 35°C, resp. for MIP and 78 mg/g, 98 mg/g and 120 mg/g at 19°C, 25°C and 35°C, resp. for NIMP. The mechanism of adsorption of α-naphtholphthalein onto MIP and NIMP is nearly appropriate to pseudo-first-order kinetic model with an activation energy of 11.63 kJ/mol for MIP and 23.69 kJ/mol for NIMP. Thermodn. parameters of activated complex in the adsorption process showed that the adsorption was carried out with an endothermic activation enthalpy, large neg. entropy changes and the pos. values of ΔG* that the adsorption processes is not favorable.
