Abstract

The objective of the present study is to investigate the mechanism of tetracyclines and macrolieds absorption on Taihu Lake sediments. In the study, batch technique was used to study the adsorptive behavior of three pharmaceutical antibiotics (tetracycline, oxytetracycline and tylosin) from several sediments of Taihu Lake, Zhushan Bay, Western Lakeshore, Lake Center, Southern Lakeshore, East Tai Lake, Eastern Lakeshore, Gonghu Bay and Meiliang Bay. The eight sediments showed extraordinarily high absorption affinity for all the tested antibiotics. However, especially the sediments of East Tai Lake was exceptional.? The observed sorbent to solution distribution coefficient (Kd, l kg-1) was 102-104. The sediment of East Tai Lake showed highest organic carbon content and cation exchange capacity. A remarkably strong sorption of antibiotics to the sediment of East Tai Lake can be attributed to the cation exchange and complexation reactions between the functional groups of antibiotics and the respective charged and polar sites of the sorbents. The sorption affinity of tetracycline and oxytetracycline from the eight sediments was higher than tylosin. Tetracycline and oxytetracycline had multiple polar and ionizable functional groups. In the study within the tested pH, the zwitterion speciation is predominated; therefore, the sorption interaction (cation exchange and surface complexation) between tetracycline and sediments was expected stronger than tylosin.
