Özet

B u çalışmada, bazik bir trifenilmetan boyası olan “kristal moru”nun CV sulu çözeltilerde H2O2 varlığında uzaklaştırılması ve bozunması, tabakalı MnO2 ve ayrıca MnO2@MnFe2O4 nanokompozit katalizörler kullanılarak araştırıldı. CV’nin bozunmasının tabakalı MnO2 yapısı ile daha hızlı gerçekleştiği görüldü. Katalitik bozunma ürünleri Elektrospray İyonlaşmalı-Dört Kutuplu-Uçuş Zamanlı Kütle Spektrometresi ESI-Q-ToF-MS kullanılarak izlendi ve analiz edildi. Ana parçalanma ürünleri olarak, biyo-iyileştirme ile mineralizasyon ürünlerine dönüşebilme potansiyeli olan 4-izosiyanobenzaldehit A ve Michler ketonu B tanımlandı. Böylece, MnO2/H2O2 sisteminin CV’yi biyobozunabilir yapılara dönüştürebilen özendirici bir katalizör olduğu anlaşıldı

Abstract

In this study, the removal and degradation of a basic triphenylmethane dye “crystal violet” CV was investi- gated by using layered MnO2 and MnO2 @MnFe2O4 nanocomposite catalysts in aqueous solutions in the presence of H2O2. The reaction was faster with the layered MnO2. The catalytic degradation of CV was traced by analyzing the degradation products using Electrospray Ionization-Quadrupole-Time-of-Flight-Mass Spectrometry ESI-Q-ToF-MS . 4-isocyanobenzaldehyde A and Michler’s ketone B were identified as main intermediates both of which can potentially be bioremediated to mineralization products. MnO2/H2O2 thus appeared to be an encouraging catalyst system in converting CV to biodegradable fragments.
