چکیده
|
Zirconium (iv) ions were removed from aqueous solutions by using amidoximated polyacrylonitrile and effect of different adsorption parameters like solution ph and contact time were also investigated# also the products were characterized using xrd and ftir analysis to study the adsorbent features# the ftir graphs illustrate that change reveals an increment in –oh group of amp, a suitable ligand for adsorption process# zirconium peaks cannot be detectable in concentrations below 1000 ppm# also, the initial faster rate may be due to surface adsorption# in the initial stage the surface was free and the reaction proceeded at a faster rate# results showed that ph had strongest effect on adsorption capacity and maximum adsorption capacity obtained at ph=2 and the maximum adsorption capacity of zr (iv) was 199#8 mg#g-1, achieved at 318 k#
