Abstract

The present work focuses on the synthesis and application of imine-modified silica-coated mAg+netic (IM-SCM) nanoparticles. The X-ray diffraction (XRD) tests indicated the presence of highly crystalline cubic spinel mAg+netite both before and after coating with the silica. The FTIR spectra also proved the successful surface coating and imine-modification of the Fe3O4 nanoparticles. Further investigations were performed to examine the capability of the modified IM-SCM nanoparticles for simultaneous Removal of Ag++ and Cu2++ from the water samples. Atomic absorption spectrometry was used for ion determination. The best operating conditions for removing the target ions were a pH=5-9 and a stirring time=30 min. Only 20 mL of 3M nitric acid was used for stripping the ions using the IM-SCM nanoparticles. The resulting data were found to fit well with the Langmuir model, and the maximum capacity of the adsorbent was determined to be 270. 3 (± 1. 4) mg and 256. 4 (± 0. 9) mg of Ag++ and Cu2++ /g of IM-SCM, respectively. The adsorbent was successfully used for simultaneously removing the target ions from the Wastewater samples.
