Description
Summary:In this investigation, the removal of anionic dyes Indigo carmine (IC) and Fast yellow (FY) has been studied by using nanoporous magnesium aluminophosphate material as adsorbent. The synthesised magnesium aluminophosphate material was characterised by FT-IR, XRD and Nitrogen sorption analysis. To find the maximum adsorption of anionic dyes on adsorbent, the experiment was carried out at various adsorption conditions like contact time, dye concentration, temperature and adsorbent dosage. Adsorption equilibrium was achieved at 20 minutes and the adsorption was followed pseudo second order kinetics. The negative G value showed that adsorption was spontaneous. The enthalpy (H for IC = 40.28kJ/mol, FY = 40.73 kJ/mol) indicated that the adsorption was endothermic and chemisorption.
