KALİKSAREN TÜREVİ İMMOBİLİZE EDİLMİŞ MERRIFIELD REÇİNESİ İLE KAPLI QCM SENSÖRÜNDE SULU ORTAMDA 4-NİTROFENOL ALGILANMASI

Abstract

Bu çalışma, kaliksaren hidrazin amit türevi içeren Merrifield reçinesi (KIMR) ile modifiye edilmiş bir QCM sensörün sulu ortamdaki p-nitrofenol (PNF) için algılama çalışmalarını açıklamaktadır. Bu amaçla öncelikle KIMR hazırlanarak yapısı karakterize edildi ve daha sonra QCM kristal yüzeyine kaplandı. Elde edilen KIMR modifiyeli sensörün PNF algılama çalışmaları, PNF için iyi bir algılama gösterdiğini ortaya çıkardı. Böylece sulu ortamda farklı konsantrasyon ve farklı pH’larda algılama çalışmaları gerçekleştirildi.  Sonuçlardan limit algılama değerinin 0,34 mM olduğu ve en iyi algılamanın pH 10 da gerçekleştiği anlaşıldı. Ayrıca Langmuir ve Freundlich adsorpsiyon izotermlerinden KIMR’nin adsorpsiyon kapasitesi, 372 mg/g olarak hesaplandı.

Sensing of p-Nitrophenol in Aqueous Media on QCM Sensor Coated with Calixarene Derivative Immobilized Merrifield Resin

Abstract

This study describes the sensing studies of QCM sensor which modified with calixarene hydrazine amide derivative immobilized Merrifield resin (CIMR) for the p-nitrophenol (PNP) sensing in aqueous media. For this aim, first CIMR was prepared and its structure was characterized, and then it was coated onto the QCM crystal surface. The PNP sensing studies of CIMR modified QCM sensor revealed good results for PNP sensing. Thus, it was performed the sensing studies at different concentration and pHs in aqueous media. From the results, it was found that the limit of detection was 0.34 mM and optimum pH value was 10 for PNF sensing by CIMR modified QCM sensor. Moreover, it was calculated the adsorption capacity of CIMR as 372 mg/g from the Langmuir and Freundlich isotherm models.
