Abstract
Magnesium is a common water hardness source. This divalent ion can react with soap anions that reduce cleaning efficiency, resulting in high detergent consumption. The development of new low-cost metal removal adsorbents has attracted a great deal of attention. Here the adsorption behavior and the underlying kinetics of magnesium sorption on Titan yellow (TY) supported on thiourea-formaldehyde resin (TF) was investigated. The results of analyzing sorption behavior showed that the sorption environment had different effects on the sorption of Mg(II) ions. It could be found that the initial pH had the best sorption effect on Mg(II) ions, the equilibrium is reached within 115-120 min and the kinetic profiles are simulated by the pseudo-second-order rate equation (PSORE). The maximum adsorption capacity of Mg was 19.45 mg g⁻¹ at initial pH = 10.5. Under the optimal conditions, the maximum sorption capacity of Mg(II) ions reaches up to 19.45 mg g⁻¹. Therefore, TF-TY was found to be an efficient adsorbent for Mg(II) removal from water.
