摘要：

In this work, a facile method was adopted to synthesize molybdenum disulfide/reduced graphene oxide (MoS_2/rGO) composites through an L-cysteine-assisted hydrothermal technique. The as-prepared MoS_2/ rGO composites were firstly applied as adsorbents for efficient elimination of Pb(II) ions. Batch adsorption experiments showed that the adsorption of Pb(II) on MoS_2/rGO followed pseudo-second-order kinetic model well. The adsorption of Pb(II) was intensely pH-dependent, ionic strength-dependent at pH < 9.0 and ionic strength-independent at pH > ...
