Abstract:

 

Study presents the utility of magnetic poly ethyleneglycoldimethacrylate-N-vinyl-2-pyrrolidone  [m-p EG- VPN ] microspheres as an adsorbent for copper  II  ion removal from aqueous solutions. The magnetic polymer microspheres were characterized by elemental analysis, N2 adsorption-desorption isotherm tests, swelling studies, scanning electron microscope  SEM  and vibrating sample magnetometer  VSM . Adsorption studies revealed that the maximum adsorption capacity of m-p EG-VPN  microspheres was 270.3 mg/g. Besides, kinetic, isothermal and thermodynamic properties of the adsorption were also investigated.

 

Ç alışmada, manyetik poli etilenglikoldimetakrilat-N-vinil-2-pirolidon  [m-p EG-VPN ] mikrokürelerinin bakır  II  iyonlarının sulu ortamdan uzaklaştırılmasında adsorbent olarak kullanılabilirliği incelenmiştir. Manyetik polimer mikroküreler, elementel analiz, N2 adsorpsiyon-desorpsiyon izoterm testleri, şişme testleri, taramalı elektron mikroskobu  SEM , titreşimli örnek manyetometresi  VSM  ile karakterize edilmiştir. Adsorpsiyon çalışmaları sonucunda m-p EG-VPN  mikrokürelerinin maksimum adsorpsiyon kapasitesi 270.3 mg/g olarak belirlenmiştir. Ayrıca adsorpsiyon işlemlerinin kinetik, izotermal ve termodinamik özellikleri araştırılmıştır.
