摘要: The main aim of this study was to synthesize magnetic separable Nickel/powdered activated carbon (Ni/PAC) and its application as an adsorbent for removal PFOS from aqueous solution. In work, the synthesized using simple method characterized by X-ray diffractionometer (XRD), surface area pore size analyzer, vibrating sample magnetometer (VSM), high resolution transmission electron microscope (HRTEM). area, volume PAC 1521.8 m2g−1, 0.96 cm3g−1, 2.54 nm, respectively. Different kinetic models: pseudo–first-order model, pseudo–second-order three adsorption isotherms—Langmuir, Freundlich Temkin—were applied sorption kinetics isothermal behavior onto as-prepared adsorbent. rate constant model 150 ppm estimated 8.82×10−5 1.64×10−4 40% Ni/PAC, Our results demonstrated that t...
