(a) Percentage of umbelliferone sorbed on different sorbents and (b) corresponding sorption distribution coefficients, Kd. KGa-2: Georgia kaolinite; IMt-1: Montana illite; SAz-1: Arizona montmorillonite; SA-HDTMA: hexadecyltrimethylammonium-modified Arizona montmorillonite; OW: olive-mill waste; BC: biochar from OW. Measurements were conducted at an initial umbelliferone concentration of 2 mg L−1 and with a sorbent to solution ratio of 20 mg:8 mL. Error bars indicate ± s.e.m. (n = 3).
