Abstract

Bu çalışma esas olarak kurşun iyonlarının bulutlanma noktası ekstraksiyonu (CPE) prosedürü ile zenginleştirme ve alevli atomik absorpsiyon spektrometrik tayinine odaklanmıştır. Yöntemde, Pb2+ ve B6 vitamininin, önderiştirilmesinden önce, bulutlanma noktası ekstraksiyonu ile kompleksleştirilmesi sağlanmıştır. Çözelti pH'sı, yüzey aktif madde ve B6 vitamini konsantrasyonları, girişim yapan iyonlar, inkübasyon sıcaklığı ve numune hacmi optimize edilmiştir. Yöntemin gözlenebilme sınırı (LOQ) ve tayin sınırı (LOD) değerleri sırasıyla 7,88 ve 25,99 olarak bulunmuştur. CPE yönteminin validasyonu, doğal kaynak suları ve maden suları gibi su örneklerine analit eklenmesi (bilinen Pb2+ konsantrasyonu) ile sağlanmıştır.

Cloud Point Extraction Of Pb (II)-Vitamin B6 Complex In Aqueous Samples

Abstract

This study mainly centered on the preconcentration and flame atomic absorption spectrometric determination of lead ions by cloud point extraction (CPE) procedure. Complexation of Pb2+ and vitamin B6 prior to its preconcentration by cloud point extraction was achieved in the method. The solution pH, surfactant and vitamin B6 concentrations, interfering ions, incubation temperature and sample volume were optimized. The limit of quantication (LOQ) and limit of detection (LOD) values of the method were found as 7.88 and 25.99 respectively. The validation of the CPE method was achieved by the analyte adding (known concentration of Pb2+) to water samples such as natural spring waters and mineral waters.
