The role of soil components in the sorption of tetracycline and heavy metals in soils.

ABSTRACT: A natural black soil (BS) was treated to obtain three individual soils referred to as removed organic matter (ROM), removed metal oxide (ROX) and humic acid (HA), and the sorption behaviors of tetracycline (TC) and heavy metals (Cu²⁺ and Cd²⁺) on BS and three treated soils were investigated to evaluate the role and contribution of different soil components (organic matter, clay and metal oxide). The three treated soils all showed stronger sorption capacities toward TC than BS, and the sorption amount of ROM, ROX, and HA for TC was greater than that of BS by 1.2 times, 2.3 times, and 3.3 times at an initial TC concentration of 25 mg L^-1. Differently, the sorption capacity of BS for Cu²⁺ and Cd²⁺ was stronger than that of ROM. The multip
