  • Based on the batch stabilization experiments upon arsenic (As) contaminated soil samples with three concentration levels (WSL, WSX, and FZ), As stabilization performance of Fe/Mg compound-typed (F2M), Ca/Fe compound-typed (CF), and MetaPro©-ani(As) typed (MPA) stabilizers were tested, and the effect of stabilizer dosage on stabilization performance were further analyzed. The materials with better stabilization effects were selected for engineering construction verification (based on FZS soil sample). The As leaching concentrations of WSL, WSX, FZ, and FZS soil samples turned to be: FZ > FZS > WSX > WSL. The results showed that: for WSL and WSX soil samples with low/medium concentration, F2M and CF typed stabilizers presented good remediation performance with low dosages; for FZ soil samples with high concentration, MPA series stabilizers showed much better stabilization performance than the former two composite ones; for the actual construction samples of FZS soil samples with high concentration, MPA series stabilizers achieved ideal stabilization effect under the open condition, with the best performance of MPA-Ⅰ typed stabilizer.
