Description

For investigating the chemical behavior of uranium-contaminated soil solidified by microwave sintering, the product consistency test method was adopted. The effective factors such as soil species, soil composition, temperature, pH values and their coupling effects have been researched. The maximum leaching rate of uranium was below 1.7 × 10-8 g m-2 day-1 and the cumulative fraction of leached uranium was below 0.0165 after 42 days. The acidic or alkaline leachate and higher temperature would enhance the uranium's leaching rate, and it was found that the chemical stability of solidified soil is related to the molar ratio of Al2O3/SiO2.
