Experimental design approach for optimization of Pb(II) removal from aqueous solution using poly-o-toluidine/stannic(IV) triethanolamine as adsorbent

Assessment of ampicillin removal efficiency from aqueous solution by polydopamine/zirconium(iv) iodate: optimization by response surface methodology

“…Recently, RSM is used in the adsorptive removal processes for optimization of independent variables and determination of relative signicance of several parameters. [53][54][55][56] The aim of this work was to develop polydopamine/zirconium(IV) iodate (PDA/ZI) for ampicillin removal from water. The composite material was characterized by different analytical techniques including Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning/transmission electron microscopy (SEM/TEM), and thermogravimetric analysisdifferential thermal analysis (TGA-DTA).…”

Sustainable environment through using porous materials: A review on wastewater treatment

“…The removal efficiency of Cr 6+ ions reached 99% due to the high specific surface area of the designed adsorbent (442.986 m 2 /g). 62 In addition, other designed adsorbents were used for metal ions adsorption, [63][64][65][66][67][68] also with chitosan/Fe 3+ hydroxide to remove Nd ions from aqueous solutions 69 or non-crystal hydrated calcium silicate gel for Pb 2+ ions removal from an aqueous solution. The latter achieved a removal efficacy of about 90% due to its moderate surface area of 128 m 2 /g.…”
