WebAug 26, 2024 · The As release curve by the TCLP test and the percolation column test showed a linear relationship with a strong correlation (R 2 = 0.9547). When compared to the percolation column test, the TCLP test resulted in a higher volume of As released from soils. The TCLP results for As release from the various soils were higher by 1.4–3.4 mg/kg.
