摘要：

Adsorption of amido black by calcined and uncalcined hydrotalcite was investigated. The influence of contact time, pH of the dye solution and adsorbent dose has been studied. In the light of so called "memory effect", the removal of amido black, an anionic dye from aqueous solution by calcined hydrotalcite was also investigated. The results of adsorption experiments indicate that the percentage removal of amido black increased with increase in contact time and adsorbent dose but decreased with the increase in pH of the solution. Calcined hydrotalcite showed better adsorption capacity compared with uncalcined hydrotalcite. The isotherms showed that the adsorption of amido black was well fitted with Langmuir equation. The present study showed that hydrotalcite can be used as an adsorbent for the removal of amido black from aqueous solution. Better percentage removal of amido black performed by calcined hydrotalcite is due to their reconstruction of original layer in aqueous solution with good ion exchangers.
