Bazı katyon değiştirici reçinelerin Pb(II), Cd(II) ve Co(II) iyonlarını bağlama özelliklerinin incelenmesi

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.

Investigation of bonding properties of Pb(II), Cd(II) and Co(II) ions in some cation exchanger resins

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.
