Hybrid nanosheets composed of molybdenum disulfide and reduced graphene oxide for enhanced solid phase extraction of Pb(II) and Ni(II)
Non-modified molybdenum disulfide (MoS 2 ) is known to adsorb heavy metal ions. However, in case of very small particle sizes and high dispersibility, ordinary centrifugation and filtration fail to separate MoS 2 from aqueous media, and this limits its applicability to solid-phase extraction. To ove...

from aqueous media, and this limits its applicability to solid-phase extraction. To overcome this shortcoming, the authors have prepared a nanocomposite consisting of MoS

and sheets of reduced graphene oxide (r–GO). The material was obtained by a hydrothermal reaction between sodium molybdate and L-cysteine in the presence of GO sheets. The results of characterizations show the MoS

nanosheets to be well dispersed on the surface of r-GO sheets. The nanocomposite was applied to the preconcentration of Pb(II) and Ni(II) ions as representative examples of heavy metal ions. The adsorption capacities are 322 and 294 mg.g
−1
for Pb(II) and Ni(II), respectively. The ions were quantified by atomic absorption spectrometry, and the respective detection limits are 0.71 and 0.21 μg⋅L
−1
, respectively. The relative standard deviations are ±2.2 % for both ions. The method was successfully applied to the preconcentration of the analytes in (spiked) urine, saliva and water samples.
