چکیده
|
A new sorbent composed of 3-aminopropyltriethoxy-silane-coated magnetic nanoparticles, functionalized with rhodium(iii) porphyrin complex was synthesized and characterized by elemental analysis, x-ray diffraction (xrd), transmission electron microscopy (tem), fourier transform infrared spectroscopy (ft-ir) and thermogravimetric analysis (tga). the effect of some co-existing anions present in aqueous solutions, ph, sorbent dosage and contact time on the thiocyanate removal was investigated. thiocyanate adsorbing material was regenerated with 15 mm naoh up to 97.0 %. the effectiveness and feasibility of the proposed sorbent for removal of thiocyanate ions from aqueous solutions is proved.
