Batik industry is well known in the East Coast of Malaysia, particularly in Terengganu and Kelantan. This industry consumes a lot of water for the batik making process which contributes to high discharge of wastewater containing excess dye pollutants. Hence, in this study, an anionic clay of nickel/aluminium-layered double hydroxide (NiAL) was investigated as a potential adsorbent for the removal of anionic dye of Eriochrome Black T (EBT). The NiAL was synthesized via self-assembly method and characterization of NiAL was carried out using powder X-ray diffraction (PXRD) and Fourier transform infrared spectrophotometer (FTIR). The composition and morphology of NiAL was further analyzed using carbon, hydrogen, nitrogen, sulphur elemental analyzer (CHNS), thermogravimetric analyzer (TGA) and scanning electron microscope (SEM). The potential of NiAL as an adsorbent for the removal of EBT in aqueous solution was tested at different dosages of NiAL. The adsorption ability was analyzed by using two common adsorption isotherms, which were Langmuir and Freundlich models. The adsorption of EBT onto NiAL was governed by Freundlich isotherm model indicating that the adsorption occurs in heterogeneous system.
