The calcination product of Mg–Al–Fe hydrotalcite compound at 500°C (HTlc500) was used as the adsorbent to remove fluoride ions from aqueous solution, while the Mg–Al–Fe hydrotalcite compound was synthesized by co-precipitation method. The hydrotalcite-like compounds (HTlcs) were characterized by XRD, FT-IR, TG-DTA, SEM, TEM, BET and pH PZC analysis. The characteristics showed that the HTlc500...
The magnetic-chitosan particle was prepared and characterized by the SEM, XRD, FT-IR and employed as an adsorbent for removal fluoride from the water solution in the batch system. The Langmuir isotherms, Bradley's isotherm, Freundlich isotherm and Dubinin–Kaganer–Radushkevich (DKR) isotherm were used to describe adsorption equilibrium. The kinetic process was investigated using the pseudo-first-order...
