ANALYSIS METHOD OF ARSENIC-CONTAMINATED SOIL OR ARSENIC-CONTAMINATED WATER

摘要

PROBLEM TO BE SOLVED: To provide an analysis method of arsenic-contaminated soil or arsenic-contaminated water capable of analyzing simply and quickly the arsenic concentration in the arsenic-contaminated soil or the arsenic-contaminated water at a site where the arsenic-contaminated soil or the arsenic-contaminated water is sampled.;SOLUTION: The arsenic concentration in the arsenic-contaminated soil or the arsenic-contaminated water is analyzed as follows: a solution containing trivalent iron ions is added to an eluate or containing liquid of the arsenic-contaminated soil or to the arsenic-contaminated water and agitated; a water-soluble magnesium salt and water-soluble calcium salt are added to a mixture acquired by agitation, and a polymer coagulant is added to generate coagulating sedimentation; a coagulated sediment is extracted and dried; the coagulated sediment acquired by being dried is crushed; the crushed sample is irradiated with a fluorescent X-ray, to thereby measure an arsenic quantity included in the crushed sample; and the arsenic concentration in the eluate or the containing liquid or in the arsenic-contaminated water is calculated based on the measurement result.;COPYRIGHT: (C)2009,JPO&INPIT
