...…(T-PL) and wheat straw (T-WS) biochars, produced at 400 C over 120–420 min and hydrothermal poultry litter and swine solids chars at 250 C under autogenic pressures for 20 h were made to remove phenanthrene (Phen), bisphenol A (BPA), and 17a-ethinyl esteradiol (EE2) from water (Sun et al., 2011)....

...On the contrary, removal of polar insecticide and herbicide compounds (e.g., 1-naphthol, norflurazon and fluridone) takes place due to polar specific interactions, e.g., H-bonding between pollutants and the functional groups of biochar produced at <350 o C (Chen and Chen, 2009; Sun et al., 2011)....
