The chemical states of arsenic contained in 4 kinds of sewage sludge incineration ash and insolubilized materials are analyzed using a leaching test (Japan environment agency notification no. 46: JLT-46), X-ray absorption fine structure spectroscopy, ion chromatography inductively coupled plasma mass spectrometry, and a chemical equilibrium model calculation. The arsenic in samples mainly exists as As(V). Three of the four kinds of insolubilized materials meet the environmental quality standards for soil after hydroxide calcium insolubilization treatment, and it is suggested that the arsenic formed Ca3(AsO4)24H2O. Two kinds of insolubilization material meet the standards after iron(II) sulfate treatment, and it is inferred that arsenic was absorbed onto iron hydroxide.
