Abstract

Layered double hydroxides (LDH) are lamellar mixed hydroxides containing positively charged main layers and undergoing anion exchange chemistry. In this study, Mg-Al-NC>3 LDH was synthesized with final Mg2+/Al3+ ratio of 2 and 3 by coprecipitation method. The adsorption of Reactive Orange 16 from aqueous solution was carried out using LDH as low-cost adsorbent. The adsorption behavior of Reactive Orange 16 dyes on LDH was investigated using a batch technique colour measurement was carried out using UV-Vis spectrometric. The adsorption processes were studied which includes contact time for adsorbent dosage (0.01 g) and different concentration. The dye adsorption equilibrium was attained with 420 min of contact time for ratio 2 and 3. Percentage of adsorption increased with increased in contact time. The adsorption capacity data were also fitted to Langmuir and Freundlich equation as well. Adsorption experiments confirmed that LDH was effective in removing of Reactive Orange 16 from aqueous solution.
