- •
Simultaneous analysis of three OTPs in environmental samples by HPLC-ICP-MS.
- •
Sorption isotherms of three OTPs on sediments were followed the Henry model.
- •
Sorption kinetic of the OTPs on sediment obeyed the pseudo 2nd-order kinetic model.
- •
External mass transfer of particles was the rate-controlling of the adsorption.
- •
OTPs could moderately degrade in anaerobic or aerobic water-sediment system.
