Abstract
Novel three-dimensional hierarchical flower-like calcium sulfate microspheres (CSMs) were successfully prepared with the assistance of polyethylene glycol, trisodium citrate, and polyacrylic acid. The CSMs were monodispersed as flower-like microspheres constructed from interspersed nanosheets. Their average diameter and Brunauer–Emmett–Teller specific surface area were 15 μm and 16.09 m2/g, respectively. The prepared CSMs were employed as adsorbents in cadmium (Cd(II)) removal from wastewater and their Cd(II) adsorption performances were analyzed. The adsorption kinetic data were best fitted to the pseudo-first-order kinetic model and the experimental isotherm data were precisely fitted to the Freundlich isothermal model. The maximum adsorption capacity of the CSMs could reach up to 18.13 mg/g at 293 K under neutral conditions, affirming the potential utility of the CSMs in Cd(II) removal from wastewater.
