a, c, e, g Removal percentage of various cations by exfoliated TMD (MoS2, WS2, TaS2, TiS2) nanosheets in individual ion solution (~2 mg L−1). b, d, f, h The corresponding distribution coefficients Kd for various cation species. Pb2+ removal by exfoliated TMD nanosheets in the presence of Na+, Ca2+ or tap water impurities (i: MoS2, j: WS2, k: TaS2, l: TiS2). DI, Deionized water. m Isotherm of Pb2+ adsorption by TMD (MoS2, WS2, TaS2, TiS2) nanosheets. Ce represents the equilibrium concentration. n Kinetics curve of Pb2+ adsorption by TMD (MoS2, WS2, TaS2, TiS2) nanosheets, inset shows the enlarged detail for the range of 0–1 min. o Overall performance comparison between MoS2 and representative adsorbents for Pb2+ removal. p Comparison of the maximum adsorption capacity (qmax) and distribution coefficient (Kd) of TMD (MoS2, WS2, TaS2, TiS2) nanosheets developed in this work (see inset shadings) with those of other benchmark materials reported in the literatures. The details can be found in Supplementary Table 5.
