Application of Box–Behnken design and desirability function in the optimization of Cd(II) removal from aqueous solution using poly(o-phenylenediamine)/hydrous zirconium oxide composite: equilibrium modeling, kinetic and thermodynamic studies

Environmental Science and Pollution Research

  • In this research work, poly(o-phenylenediamine) was incorporated into the hydrous zirconium oxide matrix to form poly(ophenylenediamine)/
  • hydrous zirconium oxide composite which is used for the removal of Cd(II) from aqueous solution. The
  • characterization of the material was done based on FTIR, XRD, SEM, and TGA-DTA. The effects of contact time, pH, adsorbent
  • dose, and initial concentration of Cd(II) on the removal of Cd(II) were studied by performing 29 sets of sorption runs using Box–
  • Behnken design combined with response surface methodology (RSM). Various isotherm models were tested to describe the
  • adsorption equilibrium. The adsorption equilibrium data fitted well with Freundlich isotherm model. The maximum adsorption
  • capacity of 66.66 mg g−1 was obtained from Langmuir isotherm. The pseudo-second-order kinetic model described the adsorption
  • kinetics more accurately. Diffusion-based kinetics such as intraparticle diffusion and Bangham’s model suggested that both
  • film and intraparticle pore diffusion were involved in the adsorption process. The Elovich model pointed towards the chemisorption.
  • The investigation of desorption and regeneration suggested that the material can be used as an effective sorbent for
  • removal of Cd(II) from aqueous system.

Development of Zr(IV)—Doped polypyrrole/zirconium (IV) iodate composite for efficient removal of fluoride from water environment

Journal of Water Process Engineering

  • The present work reports the preparation of zirconium(IV)-doped polypyrrole/zirconium (IV) iodate composite
  • for fluoride removal. The composite material was characterized by FTIR, XRD, TGA-DTA and SEM coupled with
  • EDX. The effects of various experimental parameters such as pH, contact time, adsorbent dose and initial fluoride
  • ion concentration on the fluoride removal were studied in batch mode and optimized for maximum removal of
  • fluoride from water. The adsorption capacity was found to be 183.5 mg/g at pH 6.8. The adsorption isotherm
  • data were well described by Freundlich isotherm model. The results of kinetic studies indicated that the experimental
  • data fitted well with the pseudo-second-order kinetic model. The activation energy for adsorption of
  • fluoride on the adsorbent was found to be 37.04 kJ/mol. The adsorbent has been successfully applied to remove
  • fluoride from groundwater by column method.
