Transitional adsorption and partition of nonpolar and polar aromatic contaminants by biochars of pine needles with different pyrolytic temperatures.
Biochars, produced by pyrolysis of pine needles at different temperatures, were characterized by elemental analysis, BET-N2 surface areas and FTIR, and Sorption isotherms of naphthalene, nitrobenzene, and m-dinitrobenZene from water to the biochars were compared.
A novel magnetic biochar efficiently sorbs organic pollutants and phosphate.

The results illustrate that the sorption rate of a solute with biochars is controlled largely by thesolute's diffusivity in the biochar's partition phase, in which the medium compactness affects directly the solute diffusivities.

The polarity and accessibility apparently played a regulating role in the sorption of organic contaminants, and PC4 was much more accessible and compatible to polar aromatic pollutants than nonpolar aromatic pollutants.
