Özet:

 


The Interpenetrating
Polymer Network (IPN) structure was obtained by gamma radiation of solution of
polyethylene glycol (PEG)(35000MW) in an acrylonitrile (AN) to 14 and 60kGy
doses were amidoximated with hydroxylamine solution at optimum amidoximation
conditions. Effects of pH (2-10) and mNi/mIPN ratio (0.002-0.5) in Ni2+adsorption
were examined by batch process and optimum values were determined as 8 and 0.4
for both doses, respectively. Also, the effect of flow rate to Ni2+
adsorption was examined by the reflux flow process with a fixed-bed reactor at
room temperature. Optimum flow rate is determined as 6mL/s at optimum pH. Ni2+
adsorption studies were carried out in batch (pH=6 and 8) and flow (pH=8) systems.
Maximum adsorption values reached for irradiated to 14 and 60kGy doses and
amidoximated IPNs were given as 105 and 99 mgNi/gIPN in batch system (pH=6),
378 and 361 mgNi/gIPN in batch system (pH=8) and 891 and 673mgNi/gIPN in flow
system (pH=8), respectively. Maximum elution
efficiency was obtained for HCl as being 99.5% and 66.1% for IPNs irradiated
to 14 and 60kGy doses and amidoximated, respectively. FTIR results showed that
HCl caused structural deformation. Minimum elution
efficiency was obtained for (NH4)2CO3 as
being 60.1% and 58.2% for IPNs irradiated to 14 and 60kGy, respectively, by the
minimum deformation.
