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. http://pubs.sciepub.com/aees/7/6/4/aees-7-6-4.pdf microwave synthesis aluminophosphate methylene blue adsorption studies
