英文摘要	Microplastics in environments undergo aging processes and may sorb antibiotics from surrounding water. Understanding the interaction between aged microplastics and antibiotics is important to assess the impact of microplastics on environments. In this paper, the sorption of three typical antibiotics, i.e., sulfamethoxazole (SMX), sulfamethazine (SMT), and cephalosporin C (CEP-C) onto the naturally aged microplastics (polystyrene (PS) and polyethylene (PE)) derived from aged plastics samples from the coast of East China Sea and Yellow Sea, China in freshwater and simulated seawater systems were studied. The results indicated that the mixed order (MO) model provided good prediction for the kinetics data. The linear isotherm represented adequately the sorption equilibrium data in freshwater. The Kd values ranged from 0.0236 L·g−1 to 0.0383 L·g−1. In simulated seawater, only CEP-C could be sorbed onto the microplastics. The main sorption mechanisms are hydrophobic, van der Waals, and electrostatic interactions. © 2019 Elsevier Ltd
