A VENTURI- BASED SOIL DISPERSION METHOD FOR THE ANALYSIS OF RELEASABLE ASBESTOS FIBERS

摘要

The present invention provides a technique for sampling asbestos in a naturally generated asbestos area and, especially, a technique capable of minimizing consumption of human resources and time by efficiently sampling the asbestos contained in soil. According to an embodiment of the present invention, a venturi-based asbestos preprocessing method for analyzing scattering asbestos in soil is performed using: a sampling inflow device enabling a soil sample in which the asbestos exists to flow inside and moving the soil sample, flowing inside a dispersion chamber having a cavity for scattering the soil sample flowing inside into air, using a fluid circulated by a fluid circulation device; and a sample collection device connected to an area of the dispersion chamber and collecting and storing a part of an object sample which is the fluid containing the asbestos scattering into the dispersion chamber.
