dc.description.abstractVinasse based biochar was engineered by cold oxygen plasma for different treatment time between 1 and 10 min to obtain highly efficient adsorbent for Pb(II) in the aqueous solutions. The engineered biochar with largest surface area (307 m(2)/g) and primarily microporous structure was achieved when cold oxygen plasma is processed for 3 min, providing the highest adsorption capacity (481 mg/g) derived from 500 mg/L of Pb(II) solution. For the equilibrium time (90 min) and the favorite solution pH (5.0), the best-fitting isotherm model was Langmuir isotherm one with Q(o) (714 mg/g), which is superior to those of many biochar based Pb(II) adsorbents in the literature. On the basis of XRD, XPS, FT-IR instruments and surface charge measurements, the adsorption mechanisms included ion-exchange, precipitation, electrostatic attraction, cation-pi interaction and complexation. The reusable engineered vinasse biochar has also applicability to real water samples without matrix effects.en_US
