Nanoscale amorphous AlPO 4 was synthesised via a solution combustion process using C 2 H 5 NO 2 (glycine) as fuel and NH 4 NO 3 as oxidant. The effects of molar ratios of C 2 H 5 NO 2 to NH 4 NO 3 on characteristics and sorption properties of the amorphous AlPO 4 were also studied. The experimental results showed that the Brunauer–Emmett–Teller specific surface areas of the amorphous AlPO 4 and the sorption capacities of Pb 2+ ions on AlPO 4 decreased appreciably with the molar ratio of C 2 H 5 NO 2 to NH 4 NO 3 varying from 1:9 to 1:12, while the average particle size of the amorphous AlPO 4 exhibited no appreciable change.
