Bu çalışma, poli(etilenglikol-dimetil metakrilat)
(PEG-DM) birimlerini çapraz olarak içeren altı çeşit polistiren katyon
bağlayıcı reçinenin (R) Pb(II), Cd(II) ve Co(II) iyon bağlama özellikleri ele
alındı. Reçinelerin mikro boncukları 150-200 µm çapındadır. Şişme oranları,
iyon değiştirici kapasiteleri, başlangıç metal iyonu konsantrasyonları,
yarışmalı iyon değişimi özellikleri ve reçinelerin rejenerasyon oranları
araştırıldı. İyon değiştiricilerin çapraz bağlanma derecesi arttıkça iyon
değiştirme kapasiteleri azalır. Katyon bağlama kapasiteler 3,29±0,22 ile
2,28±0,18 meq/g arasında bulundu. pH’nın iyon değişim sıraları ve kapasiteleri
üzerinde karmaşık etkileri vardı. PEG-DM reçineleri R-PEG-DM- (400, 600, 1000,
1500, 10000, 35000) için metallerin başlangıç konsantrasyonunun etkisi Pb(II)
> Cd(II) > Co(II) olarak bulundu. 400-35000 değerleri PEG’ün mol
kütleleridir. Rejenerasyon oranları, R-PEG-DM-600’de Cd(II) için en az
%88,13±1,48, R-PEG-DM-1500'de Cd(II) için maksimum % 92,12±2,85 bulundu.

This study deals with the
properties of ion exchange by Pb(II), Cd(II), and Co(II) on six different polystyrene
cation exchanger resins (R) containing poly(ethylene glycol-dimethyl
methacrylate) (PEG-DM) units as cross linkers. Micro beads of resins are 150-200
mm in diameter. Swelling
ratios, ion exchanger capacities, initial metal ion concentrations, competitive
ion exchange properties and regeneration ratios of resins were investigated.
Ion exchangers’
capacity shows a decrease with the increase of the degree of cross-linking. The maximum and minimum capacities were 3.29±0.22 and 2.28±0.18 meq/g, respectively.
There were complex effects of pH on the ion exchange orders and capacities.
Effects of initial concentration of metals were Pb(II) > Cd(II) > Co(II)
for the R-PEG-DM-(400, 600, 1000, 1500, 10000, 35000) resins. Molar masses of PEG were in the range
of 400-35000. The regeneration
ratios were minimum 88.13±1.48% for Cd(II) on R-PEG-DM-600 and maximum 92.12±2.85% for Cd(II) on
R-PEG-DM-1500.
