Title:
ハロゲン化有機化合物の抽出方法
Document Type and Number:
Japanese Patent JP6864265
Kind Code:
B2
Abstract:
This method comprises adding an aqueous potassium hydroxide solution to a body fluid such as serum, and heating the body fluid at 80°C for 15 minutes using a hot water bath to prepare a treated body fluid. When the treated body fluid and ethyl acetate are added from an inlet (211a) of an extraction part (213) to a diatomite layer (221) of a treatment layer (220), and then n-hexane is supplied to the inlet (211a), the n-hexane passes through the diatomite layer (221), a dehydrating agent layer (222), a sulfuric acid silica gel layer (223), and a silica gel layer (224), and becomes a solution in which a halogenated organic compound has been extracted from the treated body fluid. Contaminant components contained in the treated body fluid are mainly removed by being captured by the diatomite layer (221), the sulfuric acid silica gel layer (223), and the silica gel layer (224), and water contained in the treated body fluid is removed by being absorbed by the dehydrating agent layer (222).
