Abstract

In this study, the long-term stability of KEtX/Cu(OH)₂ matrix under early-period and late-period landfill leachates was evaluated using semi-dynamic leaching test (SDLT), X-ray diffractometer (XRD) and fourier transform infrared (FTIR) techniques. The results of SDLT aAer 60-day periods of extraction indicated that the cumulative leaching of Cu was only 0.72% and 3.34% of the total Cu in the KEtX/Cu(OH)₂ matrix under early-period and late-period landfill leachates, respectively. The investigation of crystallinity and functional groups between the leached KEtX/Cu(OH)₂ matrices after 1-day and 60-day periods of extraction using XRD and FTIR indicated that the KEtX/Cu(OH)₂ matrices were perfectly unaffected by the extraction using early-period and late-period landfill leachates during the 60-day leach time. Consequently, the KEtX/Cu(OH)₂ matrix had a stabilizing behavior extracted in landfill leachates.
