Тезис

This document specifies a standardized laboratory-scale test method for evaluating the performance of fine bubble-assisted washing processes for the removal of heavy metals from contaminated soils. The method involves batch experiments using fine bubble generators to facilitate the desorption and extraction of heavy metals from soil particles into a washing solution. The test method is applicable to soils contaminated with heavy metals such as lead (Pb), cadmium (Cd), copper (Cu), zinc (Zn), arsenic (As), and chromium (Cr). It can be applied to a wide range of soil types including sandy, loamy, and clayey soils for comparative evaluation of different fine bubble technologies, performance testing, laboratory validation, and certification purposes.
