Study of the adsorption process of textile dye AG1 by a mixed oxide derivative of anionic clay

Layered double hydroxides (LDH) are anionic clays with high anion exchange capacities. Calcination of LDH increases significantly their retention capacities. In the present study, calcined products (CLDH) were obtained by heating [Zn2-Al-CO3] at 500°C. The adsorption of the textile dye Acid Green 1 (AG1) by CLDH was performed at different pH values, the textile dye-adsorbent contact time and mass ratio AG1/CLDH. The equilibrium at room temperature is reached after 24 h, this is confirmed by...
