“…Even so, organic materials have appreciable capacity to sorb macrolides (Sibley and Pedersen, 2008; Pei et al, 2014; Guo et al, 2016). Therefore, removal of organic matter might be expected to reduce sorption, particularly where low charge minerals are left.…”

“…The magnitude of sorption is positively related to surface area, and sorption is nonlinear and typically described by the Freundlich model (Rabølle and Spliid, 2000;Allaire et al, 2006;Clay et al, 2005;ter Laak et al, 2006b;Sassman et al, 2007;Zhang et al, 2011;Srinivasan et al, 2014;Rath et al, 2019). Even though sorption kinetics are fast, desorption is hysteretic (Pei et al, 2014;Rath et al, 2019), indicating comparatively slow desorption kinetics and possible irreversible binding (Rabølle and Spliid, 2000;Clay et al, 2005). However, apparently irreversible sorption may, in part, reflect degradation (Feitosa-Felizzola et al, 2009).…”

“…Besides type of sorbent and solution pH, increasing ionic strength and the presence of di-and trivalent cations decrease tylosin sorption onto soil and mineral surfaces (ter Laak et al, 2006b;Essington et al, 2010;Guo et al, 2014;Pei et al, 2014;Stromer et al, 2018), indicating that sorption of the positively charged form is a competitive, outer-sphere process (Essington et al, 2010;Pei et al, 2014). In contrast, although Srinivasan et al (2014) found no relation of tylosin sorption with cation exchange capacity (CEC) or organic carbon (OC), sorption likely involved complexation of tylosin carbonyls (Feitosa-Felizzola et al, 2009).…”

Sorption and Desorption Characteristics of Tylosin in Three Louisiana Soils

The macrolide antibiotic tylosin is widely used in animal production, but its environmental fate is not fully understood. Objectives of this study were to determine the effect of pH on tylosin A sorption and desorption in three sandy loam soils from Louisiana, USA, that had long histories of poultry waste application, to model sorption and desorption, and to estimate the effect of high soil organic matter on sorption. Twenty‐four‐hour sorption isotherms (5 to 200 mg L−1 in 0.01 M CaCl2) at pH 4.5, 6.0, and pH 7.5 were described by the Freundlich model. Desorption from the 200‐mg L−1 set at constant pH by 10 24‐h extractions with 0.01 M CaCl2 recovered 43 to 98% of the added tylosin A, and further desorption with methanol increased recovery from 66 to 100%. Single‐point distribution coefficient, KD, as a function of pH from 4 to 9 in 0.01 M CaCl2 exhibited maxima from pH 6 to 7, reflecting increasing sorption of the positively charged form with increasing pH up to about the pKa. The data were well described, modeling pH‐dependent negative charge according to Henderson–Hasselbalch along with tylosin speciation. Using soil from which organic matter had been removed by H2O2 gave three to six times greater KD at pH 6 to 7, but without or with reduced maxima. The data could be approximately described without invoking pH‐dependent surface charge. Further study is needed to confirm whether an increase in soil organic matter with poultry waste application decreases tylosin sorption, thus increasing environmental risk. Core Ideas Sorption is pH dependent and desorption is partly irreversible. Sorption exhibits a local maximum in pH 6 to 7. Removal of soil organic matter greatly increases sorption.

“…Therefore, studies on co-sorption of antibiotic and heavy metal on soil could facilitate to further improve our understanding of combined pollution risks. In detail, metal ions enhance the sorption of antibiotics in soils through the formation of a soil-metal-antibiotic ternary surface complex or electrostatic attraction; [16][17][18][19] On the other hand, metal ions suppress the sorption of antibiotics due to competition for sorption sites between positively charged antibiotics and metal ions at low pH. [19][20][21] At the same time, the presence of metal ions also results in changes of the soil properties and structure, such as potential, pore size and content of oxides, then coming into different sorption mechanisms for antibiotics.…”

The adsorption process of the pharmaceutical pollutant in the soil is affected by its physicochemical properties and soil properties. In this study, the factors affecting the adsorption of tetracycline and diclofenac onto two different soils (S and M) were investigated using response surface methodology (RSM). The RSM design was used to optimize the five variable factors (pH (2–10), contact time (5–180 min), soil amount (1–10 g/L), temperature (25–45°C)) on the adsorption of tetracycline and diclofenac. The predicted optimal conditions obtained by RSM showed that pH was the most important variable affecting the adsorption of tetracycline and diclofenac. The optimum pH for the adsorption of tetracycline and diclofenac onto the soil samples S and M were found to be 4 and 2, respectively. The adsorbed amounts of tetracycline and diclofenac onto the soils S and M were calculated to be 14.82 mg/g, 12.43 mg/g, 189.40 mg/g, and 144.81 mg/g, respectively. In addition, the effects of soil organic matter, salt, and divalent cations on the adsorption of tetracycline and diclofenac onto soils were studied. The removal of soil organic matter slightly increased tetracycline adsorption, while inhibiting diclofenac adsorption. The presence of salt and divalent cations prominently suppressed the adsorption of tetracycline and diclofenac onto soils. A possible complex mechanism was proposed for TC and DCF adsorption, including ion exchange, electrostatic interaction, and some chemical bonds.
