Abstract
Sorption studies of Cu2+ ions onto AlPO4 were carried out as a function of pH (3–5) and temperature (303–323 K). The extent of sorption was found to increase with an increase in Cu2+ ion concentration, pH and the temperature of the system. The Kurbatov equation along with a new equation based on the law of mass action were found applicable to the sorption data. The sorption mechanism was found to consist of an exchange between the H+ ions from the exchanger and Cu2+ ions from the aqueous solution. The thermodynamic parameters evaluated showed that the process was endothermic and non-spontaneous in nature. FT-IR spectroscopy was also employed to evaluate the mechanism of Cu2+ ion sorption.
