This research quantified thermodynamic parameters to better understand the use of wastewater biosolids-derived biochar as an adsorbent to remove micropollutants. The objective of this research was to quantify adsorption capacity; isosteric heat; and change of enthalpy, entropy, and free energy characterizing adsorption reactions between biochar and micropollutants. Adsorption isotherms were developed using a range of temperatures for the micropollutants benzyldimethyldecylammonium chloride (BAC-C10) Carbamazepine (CBZ), 17β-estradiol (E2), 17α-ethynylestradiol (EE2), and triclosan (TCS). The thermodynamic parameters derived from the isotherm data were used to assist in characterizing binding affinity, spontaneity, and mechanisms of adsorption. More polar compounds such as BAC-C10 and CBZ …
