Abstract

Abstract: A new MoS2 /Fe3 O4 dendrimer grafted polystyrene (PST)/poly(N-vinylcaprolactam) (PNVCL) was prepared as a temperature-sensitive nanocomposite for adsorption and controlled release of sertraline. The maximum adsorption capacity of nanocomposite for sertraline was about 5.24 mgg −1 under optimum pH of 8, equilibrium time of 30 min and adsorbent dosage of 5 gL −1 . The kinetic of sertraline sorption follow the pseudo-second-order kinetic model, and the corresponding isotherm was well fitted with the Redlich–Peterson isotherm model. The highest release of sertraline was obtained at 50 °C during 24 h. The non-Fickian diffusion of the sertraline release from nanocomposite was achieved at 37 and 50 °C. Graphical abstract: UF0001
