Zusammenfassung:The objective of this research is to synthesis of Mg/Al hydrotalcite-like (Mg/Al HTlc) from brine water and itsapplication as a methyl orange (MO) removal. The research initiated with the synthesis of Mg/Al HTlc from brinewater, which is well known as the desalination process wastewater. Characterization of the Mg/Al HTlc synthesizedwas confirmed through X-ray Diffraction and FT-IR Spectroscopy. The determination of optimum acidity, adsorptionrate, and energy and capacity adsorption were studied. The result showed that pH 4 was the optimum acidity for theadsorption of MO on Mg/Al HTlc. MO was adsorbed at pseudo-second order adsorption rate of 1.03 × 105 g mol-1 min-1on the Mg/Al HTlc. The adsorption data fitted well into the linearly transformed Freundlich equation
