ABSTRACT:

The potential feasibility of anionic clay hydrotalcite for removal of eriochrome black dye from aqueous solution was investigated. The effects of various experimental parameters such as contact time, pH and adsorbent dosage were investigated. The extent of eriochrome black dye removal increased with the increased in contact time, pH and amount of adsorbent used. Adsorption data was fitted to the Langmuir adsorption isotherm. The results in this study indicated that anionic clay layered double hydroxides was an attractive adsorbent for removing eriochrome black dye from aqueous solution.

KEYWORDS:
