Description
To develop a new agent for immobilization of lead form fly ash, AlPO4 was synthesized from a phosphorus-rich solution from chicken manure incineration ash and Al(OH)3 solution as aluminum effluent. The ability of synthesized AlPO4 to immobilize lead from fly ash was evaluated. The synthesized AlPO4, with high rates of filtration and phosphorus recovery, could be obtained at the L/S of 5 and a pH of less than 1 for extraction of phosphorus solution from the chicken manure incineration ash with sulfuric acid and at the pH of 5 for synthesis using Al(OH)3 solution. The result of JLT 13 showed that the synthesized AlPO4 had the same high lead immobilization ability as that of commercial AlPO4 on the basis of added phosphorus to the ash. In addition, from result of availability test on pH4 suggested that aluminum phosphate has a high lead immobilization ability under acid condition. Amorphous aluminum phosphate is an effective immobilization agent for heavy metal such as lead in scrubber residues.
