Abstract
In this paper, we investigated the kinetics and thermodynamics of phosphorus adsorption by a new efficient phosphorus removal composite (EPRC). Kinetic analysis showed that the adsorption of phosphorus by EPRC is best described by a pseudo-first-order equation. Thermodynamic analysis showed that the Gibbs free energy (ΔG°) is negative, implying that the reaction is spontaneous. Moreover, the change in enthalpy (ΔH°) of phosphorus adsorption by EPRC was always greater than 60 kJ/mol, indicating that the adsorption was an endothermic chemical process. Furthermore, EPRC adsorbs phosphorus better at higher temperatures.
