Paper Title:
Adsorption of Dye from Aqueous Solution by Zn-Al Calcined Layered Double Hydroxide
  Abstract

The adsorption of C. I. Reactive Red 2 from aqueous solution on Zn-Al calcined layered double hydroxide (CLDH) was investigated. Experiments were carried out as a function of Zn-Al molar ratio, contact time, pH, temperature and initial dye concentration. The results showed that Zn-Al calcined layered double hydroxide had higher capacity of removal of the dye. Zn-Al CLDH with Zn-Al molar ratio of 3 and with pH range of 4.0-8.0 was found to be optimal for dye removal. Adsorption capacity of dye decreased with increasing temperature and increased with increasing initial dye concentration. It was found that the adsorption equilibrium data followed the Langmuir adsorption model. The maximum adsorption capacity obtained from the Langmuir equation at temperature of 30°C was 116.28mg/g (R2=0.9992) for the dye.
