ABSTRACT Background Sulfonamide antibiotics have been discovered as emerging pharmaceutical pollutants worldwide and are only poorly removed in wastewater treatment. At the landscape level, peat soils significant water collectors and, thus, sinks for organic pollutants. However, fate of pharmaceutically active contaminants soil is, yet, largely unclear. Aim Factors regulating sorption a dominant process that influences filtering buffering sulfonamides sulfadiazine (SDZ) sulfamethoxazole (SMX) different were investigated. Methods The SDZ SMX was investigated batch experiments using with physicochemical properties under land use, including sustainable wet peatland cultivation (paludiculture). Results Sorption K d values ranged from 21.39 to 102.8 mL g −1 11.23 107.3 SMX. Soil pH, carbon content, C/N ratios significantly correlated sulfonamides. Non‐linear regression analyses showed Freundlich isotherm model generally best suited describe both (0.54 ≤ R 0.98). n 1 sulfonamides, indicating co‐mechanistic opposed partitioning alone. A quantitative structure–property relationship (QSPR) constructed predict good cross‐validated performance ( 2 adj = 0.79, root mean squared error [RMSE] 8.71). Conclusions sorptive capacities higher than those many terrestrial soils. quantity stoichiometric matter fraction, well pH conditions, affect ability immobilize these antibiotics.
