elution volume estimation method to the water system of heavy metal elements such as derived from the natural

摘要

PROBLEM TO BE SOLVED: To provide a method for estimating an elution amount of heavy metal elements or the like to a water system for a long period along with a simulator of water quality change.;SOLUTION: An estimation method is performed along with a simulation of a water quality change for simulating the water quality change including at least pH information of a water system by a chemical analysis of a sample collected from soil or the like. The method includes the steps for: obtaining an ideal elution amount of each of the heavy metal elements and an amount of ferric hydroxide sedimentation corresponding to the water quality change from inclusion information of heavy metal elements or the like obtained from the chemical analysis; obtaining an adsorption amount of the heavy metal elements or the like to be absorbed corresponding to the amount of sedimentation; and estimating the elution amount of the heavy metal elements or the like by subtracting the adsorption amount from the ideal elution amount.;COPYRIGHT: (C)2013,JPO&INPIT
