Abstract

In this work we present a novel procedure for ibuprofen adsorption from waters employing magnetic core-modified silver nanoparticles. We demonstrate that 93% adsorption of ibuprofen is achieved in 45 min by means of a simple method, for neutral pH and room temperature, also using a low dose of adsorbent, equal to 7 mg in 500 µL of suspension. The characterization of the adsorbent, before and after adsorption, was carried out by means of field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, BET analysis, Fourier-transform infrared spectroscopy and differential scanning calorimetry. It is worth pointing out that ibuprofen can be desorbed and the adsorbent can be reused, remaining unaltered for the first three cycles, and showing 89.3% adsorption efficiency after the third regeneration. A three-parameter model and the Langmuir isotherm characterize the kinetics and isotherm of adsorption.

Highlights

  • In this work we present a novel procedure for ibuprofen adsorption from waters employing magnetic core-modified silver nanoparticles

  • Some of the methods to eliminate IB from water samples are based on its degradation or oxidation. In the former case, it is worth pointing out the employment of microorganisms through b­ iodegradation9, ­biotransformation[10], photocatalytic process with T­ iO211 and coagulants m­ ethods[12]

  • Magnetic core-modified silver nanoparticles ­(Fe3O4@AgNPs) have been used to adsorb ibuprofen from aqueous solutions, being a new outstanding method for reaching high removal efficiency, under very mild conditions and in a short time compared with other p­ rocedures21,37,38. ­Fe3O4@AgNPs are synthetized and removed from media using a magnet

Summary

Introduction

In this work we present a novel procedure for ibuprofen adsorption from waters employing magnetic core-modified silver nanoparticles. In the present method high adsorption efficiency is achieved under mild experimental conditions such as neutral pH and room temperature. Magnetic core-modified silver nanoparticles ­(Fe3O4@AgNPs) have been used to adsorb ibuprofen from aqueous solutions, being a new outstanding method for reaching high removal efficiency, under very mild conditions and in a short time compared with other p­ rocedures[21,37,38].
