【 摘 要 】

The textile industry is one of the swiftest thriving industries contributing to the economic growth of Malaysia, particularly in east coast peninsular state. As the popularity of industry increases, the water usage was found to be elevated and eventually causes high expel rate of wastewater with excessive dye pollutants. In this study, anionic clay of nickel/aluminium layered double hydroxide (NiAL), was chosen to be studied as a potential adsorbent for anionic dye, namely Alizarin Red S (AR). The NiAL was synthesised via co-precipitation method and were characterized using powder X-Ray diffraction (PXRD) and Fourier Transform Infrared spectrophotometer (FTIR). NiAL was then used as adsorbent for the removal of AR dye in aqueous solution which was tested at different NiAL dosages. The experimental data were analysed using adsorption isotherm models and the AR adsorption was found to obey the Langmuir model.
