The anthropogenic release of highly toxic heavy metals into the environment presents a huge challenge for ecosystems and human society. Recoverable and efficient adsorption materials could be obtained by trapping inorganic adsorbents (e.g., TiO2 nanoparticles and rectorite (REC)), in a natural polymer matrix. In this study, a series of cellulose-TiO2/REC composite nanofibrous mats were fabricated via electrospinning. The interactions between inorganic adsorbents and cellulose molecules improved the thermal stability, surface area, tensile strength and adsorption capacity of the mats. We focused on the adsorption of Pb2+, Cu2+ and Cd2+ from acidic solutions onto cellulose-TiO2/REC composite nanofibrous mats in multiple systems because the magnitudes of heavy metal concentrations in wastewater typically varied. The maximum total adsorption capacity of 69.81 mg/g was obtained by Cellulose-TiO2/REC2:1 nanofibrous mats. The composite nanofibrous mats successfully trapped TiO2 nanoparticles, and the obtained cellulose-TiO2/REC nanofibrous mats could be used to remove heavy metals from acidic wastewater.
