Propranolol removal from aqueous solution using ionic liquid-LDH nanocomposite

Propranolol is very significant drug but causes some problems and side effects for public and animals while enter to the surface water. In this work, for propranolol removal from water ionic liquid- layered double hydroxides nanocomposite were synthesized, characterized and exploited as adsorbent in aqueous medium. The propranolol in water was monitored by spectrophotometer at wavelength of 290 nm. The maximum removal of propranolol was 95% through preliminary concentration 60ppm; sonication time: 15 min., pH: 8.0, adsorbent dose: 15mg and 35 °C temperature. The sorption data modeled by Langmuir, Freundlich, and Temkin models. The thermodynamic properties; ΔG°, ΔH° and ΔS° in optimal condition and different temperature was calculated. Kinetics modeling demonstrated that the removal of propranolol followed by pseudo first order.
