CONTINUOUS FLOW-THROUGH SYSTEM FOR AEROBIC AND ANAEROBIC SOIL METABOLISM TEST

摘要

The present invention relates to an apparatus for aerobic and anaerobic soil metabolism test. According to the present invention, air within a gas cylinder is supplied inside a soil trap in which aerobic soil is stored at a constant amount and flow rate using a digital flow meter, and then volatile substance and carbon dioxide decomposed by aerobic or anaerobic soil microorganism are collected, and then metabolites of aerobic soil are analyzed, and decomposition rate of test substance and produced metabolites are measured, to check in which route the test substance is decomposed when being introduced into the soil and sediment. In the aerobic soil metabolism test device, nitrogen is charged inside a gas cylinder, and nitrogen is supplied inside a soil trap where anaerobic soil is stored, so that the volatile substance and carbon dioxide decomposed by the anaerobic soil microorganism are collected, and methane gas (CH_4) is converted to carbon dioxide to be collected, by passing through and exposed to a quartz tube filled with oxidized copper (CuO) inside an electric ashing furnace at a high temperature (800-900°C) along with externally supplied oxygen, and thereby produced amount of methane gas is measured to analyze the test substance and metabolites of anaerobic soil, and check the decomposition rate and produced metabolites of the test substance in order to check in which route the test substance is decomposed when being introduced into the soil and sediment.
