Preparation, characterization and application of a Ce-Ti oxide adsorbent for enhanced removal of arsenate from water.
TL;DR: Environmental scanning electronic microscopy and X-ray diffraction spectroscopic investigations revealed that the amorphous Ce-Ti hybrid adsorbent was composed of some nanoparticles in the size range of 100-200 nm, which aggregated to form the porous hybrid Adsorbent, and theAmorphous compositions and the small nanoparticles were related to the high sorption capacity for As(V).

Application of response surface methodology for optimization of heavy metal biosorption using surfactant modified chitosan bead
TL;DR: In this article, an ideal experimental model was developed using fractional factorial and central composite design (CCD) based on response surface methodology (RSM) among the experimental parameters viz. pH, adsorbent dose, concentration of metal, agitation time and temperature.
