Practical Remediation of Hg-Contaminated Groundwater by MoS₂: Batch and Column Tests.

ABSTRACT: Trace mercury contamination in groundwater poses a serious threat to ecological systems and human health. The kinetics and isotherms of MoS₂ (MS) for Hg removal were studied in batch tests under an unfavorable high salinity and low mercury environment. Flower-like MS with nanosheets can effectively remove Hg in the groundwater matrix, with a shorter equilibrium time (3 h), superior removal efficiency (94.26%), excellent distribution coefficient (5.69 × 10⁶ mL g^-1), and higher maximum adsorption capacity (926.10 ± 165.25 mg g^-1). Furthermore, the Adams-Bohart model (R² = 0.9052-0.9416) can accurately describe the dynamic interception process of the initial stage (≤40 PVs), and the Yan model (R² = 0.9765-0.9941)
