Water plays an essential role in our lives. It is used by all parts of our body to help regulate temperature and maintain other bodily functions. Pollution caused by industrialization and population growth has led to water shortage and it is affecting humans by lowering their quality of life. One of the main solutions for this challenge is water purification. In this study, we have used a cost- and energy-efficient novel material, two-dimensional (2D) graphene oxide (GO) to fabricate promising water purification membranes alongside with another 2D material, molybdenum disulfide (MoS2). GO has unique physicochemical properties including high surface area, mechanical durability, and nanosized pores, making it excellent water filtration membranes. GO can also decrease energy use in terrestrial and space applications. These characteristics makes GO extremely special by making it efficient in water purification on both earth and outer space. In comparison, MoS2also shows great promise for water filtration. When forming composites with GO, the water fluxes might vary significantly while the reliable structure and properties of MoS2nanochannels in the composites are largely unknown. In this work, we have focused on the structure-filtration relationship of graphene oxide-MoS2composite membranes for purifying wastewater containing arsenic and lead ions. The GO-MoS2composites were synthesized by hydrothermal reactions and the composite membranes were prepared by vacuum filtration method. The structures of the membranes were examined by various methods including TGA, XRD, and SEM. The efficiency and the permeability of the membranes for arsenic and lead ion filtration were measured by electric conductivity measurements. The discoveries from this research may have a great impact on water reuse on both earth and outer space.
