CLARIFYING AGENT FOR CLARIFICATION TREATMENT OF SOIL/GROUND WATER, METHOD FOR PRODUCING THE SAME, METHOD FOR TRANSPORTING THE SAME AND METHOD FOR CLARIFICATION TREATMENT OF SOIL/GROUND WATER

摘要

PROBLEM TO BE SOLVED: To provide a clarifying agent which can efficiently, sustainably and economically decompose and insolubilize aliphatic organic halogen compounds, aromatic organic halogen compounds, heavy metals and the like included in soil or ground water.;SOLUTION: The clarifying agent used for clarification treatment of soil/ground water is a solid obtained by freezing aqueous suspension containing iron composite particles consisting of α-Fe and magnetite. The iron composite particles have an average particle size of 0.05 to 0.50 μm, contain 3,500 to 10,000 ppm of S and 0.10 to 1.50 wt.% of Al.;COPYRIGHT: (C)2013,JPO&INPIT
