AB  - 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 K(d) 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.
