Abstract
One of the most problematic persistent and non-degradable pollutants are heavy metals, which are among the most toxic pollutants in the environment. Therefore, removing these pollutants is of particular importance. Uranium, as one of the heavy metals, is a natural radionuclide that harms human health and the environment. This is due to its serious toxicity and radiation properties. In this research, Amberlite XAD-4 resin impregnated with bis-2-hydroxybenzaldehyde 1,2-diaminoethane (H2L) Schiff base ligand was used for uranium adsorption from aqueous solution. The effect of effective parameters such as aqueous phase pH, contact time, amount of adsorbent and temperature dependence on the process was investigated. The results showed that 98% of uranium ions were absorbed under the optimal conditions of pH5.5, adsorbent amount 0.1 g, contact time 60 min. From 20 mL of aqueous solution at 25 C, uranium ions with a concentration of 20 mg/L were quantitatively removed. Comparing the adsorption percentage of non-impregnated resin with impregnated resin with Schiff base ligand shows a shift in uptake of uranium ions vs. pH curves towards lower pH values (about ΔpH0.51) and the adsorption behavior of the resin at pH5.5 improves with increasing adsorption from 52% to 98%. The kinetic and adsorption data are in good agreement with the pseudo-second-order equation and Freundlich isotherm, respectively. A thermodynamic analysis also revealed that the ion adsorption process is entropy-based.
