Abstract

Sunulan çalışmanın amacı manyetik
aljinat/perlit kompozit mikrokürelerin hazırlanması, karakterizasyonu ve
sentezlenen mikrokürelerin sulu çözeltiden kurşun ve nikel ağır metal
iyonlarının uzaklaştırılmasında kullanılabilirliğinin araştırılmasıdır.
Mikrokürelerin ağır metal adsorpsiyon kapasitesi üzerine perlit
konsantrasyonunun, başlangıç metal iyon derişiminin ve çözeltinin pH’nın
etkileri araştırılmıştır.
Demir oksit partikülleri basit çöktürme yöntemiyle, mikrokürelerin
sentezinde iyonik jelasyon yöntemi kullanılmıştır. Demir oksit içeren mikrokürelere perlit eklenmesi ile
mikrokürelerin su tutma kapasiteleri azalmıştır. SEM analizi mikrokürelerin
küremsi yapıda ve yüzeyinin pürüzlü olduğunu göstermiştir. SEM-EDX analizi manyetik
aljinat/perlit mikrokürelerin C, O, Na, Al, Si, K, Cl ve Fe içerdiğini ortaya
koymuştur. XRD analizi sentezlenen demir oksit tozunun Fe3O4 olduğunu belirtmiştir. TGA analizi
perlit ilavesi ile mikrokürelerin termal dayanıklılıklarının arttığını ortaya
koymuştur. Perlit/aljinat oranı=2 (a/a) olduğunda mikrokürelerin
adsorpsiyon kapasitesi maksimuma ulaşmış fakat bu orandan fazla perlit ilavesi
mikrokürelerin adsorpsiyon kapasitesinde azalmaya neden olmuştur.

Abstract

The goal of present study is preparation,
characterization of magnetic alginate/perlite composite microspheres and to
investigate the usability of produced microspheres for the removal of lead and
nickel ions from aqueous solution. The effect of perlite concentration, initial
metal ion level and the pH of the solution on the heavy metal adsorption
capacity of microspheres were investigated. Iron oxide particles were prepared
by simple precipitation method. Ionic gelation method was utilized to
synthesize the microspheres. Swelling studies showed that addition of perlite
to iron oxide-containing micropsheres decreased the swelling degree of the
microspheres. SEM analysis indicated that microspheres were almost spherical
with rough surface. SEM-EDX showed that
alginate/perlite microspheres composed of C, O,
Na, Al, Si, K, Cl and Fe. TGA analysis indicated that incorporation of perlite
improved the thermal properties of microspheres. Adsorption capacity of
microspheres reached the maximum value when the perlite/alginate ratio=2
(wt./wt.), but then adding more than this value significantly decreased the
adsorption capacity of microspheres.
