AI Technical Summary
Existing technologies cannot effectively simulate the migration of PFAS in multiphase flow environments containing NAPL, and there are problems such as material background interference and device complexity, making it impossible to accurately measure the migration characteristics of PFAS.
A soil column simulation system containing NAPL was designed. Fluorine-free materials were used to construct the liquid supply, core simulation, and drainage modules. Combined with a composite multi-stage flow equalization and interception component, the system simulates a multiphase flow environment, eliminates material background interference, and realizes one-dimensional piston flow.
It accurately simulates the migration of PFAS in multiphase flow environments, reduces the adsorption loss of PFAS in materials, and provides high-precision migration characteristic measurement, which is suitable for PFAS detection in soil and groundwater at different depths.
