چکیده
|
A new fibrous adsorbent was prepared by grafting acrylic acid /acryl amide (aa/aam) co-monomers onto poly(ethylene terephtalat) (pet) fibers. the resulting sorbent has been characterized by fourier transform infrared spectroscopy (ft-ir), thermo gravimetric analysis (tga), scanning electron microscopy (sem) and elemental analysis and studied for the preconcentration and determination of trace pb+2 ion from water sample. the effects of reaction conditions such as monomer mixture ratio, grafting yield, polymerization. the time and temperature on grafting were investigated. batch adsorption method was used for the pre concentration studies. recovery of pb+2 was 100.2% at optimum conditions. the adsorption capacity of the adsorbent was found 44.1mg/gforpb+2.
