Abstract

Hexa [4-(4-hydroxy-phenyliminomethyl) phenoxy] cyclotriphosphazene (A1) and Hexa [4-(2- hydroxy- phenyliminomethyl) phenoxy] cyclotriphosphazene (A2) were derived from the reactions of hexa(4- formyl-phenoxy)cyclotriphosphazene and hexa(2-formyl-phenoxy)cyclotriphosphazene with 4- aminophenol and 2-aminophenol. Adsorption process in an aqueous solution of Cu, Fe, Mn and Zn ions of the organophosphazenes bearing imine groups were performed depending on the initial concentration of metal ions and time. All of the compounds adsorbed the selected metal ions in the first 10 minutes. When the initial concentration of metal ions increases, the amount of metal ions adsorbed of organophosphazene with imine groups increased. Although the chemical structures of the compounds are different, the amount of adsorbed metal was about the same.

İmin Grupları Taşıyan Fenoksi Sübstitüe Siklotrifosfazen Türevleri ile Ağır Metal İyonları Giderimi

Abstract

Hekza[4-{(4-hidroksi-fenilimino)metil}fenoksi]siklotrifosfazenin(A1) ve hekza[4-{(2-hidroksi-fenilimino)metil}fenoksi]siklotrifosfazenin(A2), 4-aminofenol ve 2-aminofenol ile heksa (4-formil-fenoksi) siklotriposfazen ve heksa (2-formil-fenoksi) siklotriposfazen reaksiyonlarından türetildi. İmin gruplarını taşıyan organofosfazelerin sulu Cu, Fe, Mn ve Zn iyonları çözeltisinde adsorpsiyon işlemi, metal iyonlarının başlangıç konsantrasyonuna ve süresine bağlı olarak gerçekleştirildi. Bileşiklerin tümü seçilen metal iyonlarını ilk 10 dakika içerisinde adsorbe etti. Metal iyonlarının başlangıç konsantrasyonu arttığında, imin gruplarıyla organofosfazene adsorbe edilen metal iyonlarının miktarı arttı. Bileşiklerin kimyasal yapıları farklı olmasına rağmen, adsorbe edilen metal miktarı yaklaşık olarak aynıydı.
