Four commercially available chelating agents used for fly ash stabilization were collected and used to study the releasing characteristic of volatile pollutants at 20℃ and 40℃. The results showed that the released volatile pollutants were composed of formaldehyde, acetaldehyde, benzene, isovaleraldehyde/isopropanol, methyl mercaptan, ethyl mercaptan and so on. Among the volatile pollutants released from three chelating agent samples, the concentration of formaldehyde was the highest; at 20℃, the concentration of formaldehyde was 748~1325 μg/L-chelating agent, accounting for 68%~96%(mass ratio) of the released volatile pollutants; at 40℃, the concentration of formaldehyde was 4282~6822 μg/L-chelating agent, accounting for 87%~95% (mass ratio) of the released volatile pollutants. With the increase of temperature, more types of volatile pollutants were released from the chelating agents, and the concentrations of some pollutants increased. At 40℃, the concentrations of the volatile pollutants released from the four chelating agent samples increased by 142% to 444% compared with those at 20℃. Elemental analysis, Raman spectroscopy and thermogravimetric analysis showed that these four chelating agents had similar active ingredients of dithiocarbamates. It suggested that, during the storage, dilution, and fly ash stabilization processes, the pollutants released from this type of chelating agents might be harmful to the health of the operators. Emitted air pollutants should be collected for further treatment. In addition, during the fly ash landfill process, the residual chelating agents in the fly ash may increase the concentration of ammonia and other substances in the leachate, which would increase the difficulty for leachate treatment.
