Abstract

The extraction of Cd2+ ions via a new Multi-Dropped Liquid Membrane System: Extraction of Cd2+ ions from the solution phase wasstudied by using the multi-dropped liquid membrane system, which is different from other liquid membranes. The extraction of Cd2+ ionsthrough multi-dropped liquid membrane containing tri-n-octyl amine in kerosene as mobile carrier and protons as counter ions in the acceptorphase (CH3COONH4) was investigated. Donor, acceptor, and the organic phase in the reduced concentration of Cd2+ model time dependencecurves showed a good fit to experimental data obtained. The activation energy in the extraction mechanism of Cd2+ ions was calculatedto be 17.07 kcal/mol. The value of this calculated activation energy indicates that the extraction of Cd2+ ions with the multi-droppedliquid membrane system is chemically controlled. The experimental results suggest the possibility of removing Cd2+ ions from aqueoussolution in an extractor based on multi-dropped liquid membrane system.

Özet

Cd+2 iyonlarının yeni bir Çok Damlacıklı Sıvı Membran Sistemi ile ekstraksiyonu: Cd+2 iyonlarının çözelti fazından ekstraksiyonu, diğer sıvı membran tiplerinlerinden farklı olan çok damlacıklı sıvı membran sistemi kullanılarak çalışılmıştır. Çok damlacıklı sıvı membran sisteminde kerozen içinde çözünmüş taşıyıcı tri-n-oktil amin ve aksptör faz olarak karşıt iyon olan protonlayıcı (CH3 COONH4 ) içeren çözelti ile Cd+2 iyonlarının ekstraksiyonu incelenmiştir. Donör, akseptör ve organik fazdaki Cd+2 iyonlarının zamanla azalan konsantrasyon eğrileri elde edilen deneysel verilerle iyi bir uyum göstermiştir. Cd+2 iyonlarının ekstraksiyon mekanizmasına ait aktivasyon enerjisi, 17.07 kcal/mol olarak hesaplandı. Bu hesaplanan aktivasyon enerjisinin değeri çok damlacıklı membran sistemi ile Cd+2 iyonlarının ekstraksiyonunun kimyasal kontrollü olduğunu göstermiştir. Deneysel sonuçlara göre çok damlaçıklı sıvı membran sistemine dayanan bir eksraktör ile sulu çözeltiden Cd+2 iyonlarının uzaklaştırılmasının mümkün olduğunu göstermektedir.
