Abstract

The present work is concerned with synthesis of aluminophosphate zeolites with tridymit framework by employing microwave technique and alanine as structure directing agent. Aluminophosphate zeolite was characterised using XRD, SEM- EDAX, BET and FTIR. Adsorption efficiency of the synthesised aluminophosphate zeolite was evaluated using water soluble dye methylene blue as a model pollutant. Influence of pH, Adsorbent dosage, Dye concentration and contact time were studied. Experimental data fitted well with pseudo bimolecular kinetic model and freundlich’s adsorption isotherm (R²=1) with yielding a maximum adsorption capacity of 37.016ppm mg^-1.
