Linear relationships of logQ0 (a) and logQ* (c) with logSw or logSo of 25 aromatic chemicals by RS144 (as an example of humus-like substances), as well as correlations of calculated sorption capacity logQ0cal and logQ*cal with experimental sorption capacity logQ0exp (b) and logQ*exp (d) by RS144, respectively. Solid lines are the reference line, y = x. Dotted lines are the standard deviation (SD) values from the reference line.
