Abstract

Heavy metal pollution has been a major problem in drinking water all over the world. Increase in water pollution due to population growth, also inadequate municipality services, people have preferred consuming bottled water more. Hence, it is crucial to determine mineral composition of the bottled drinking water. In this study, Antimony (Sb), Arsenic (As), Beryllium (Be), Cadmium (Cd), Chromium (Cr), Cobalt (Co), Copper (Cu), Iron (Fe), Lead (Pb), Lithium (Li), Manganese (Mn), Nickel (Ni), Strontium (Sr) and Vanadium (V) were analyzed by inductively coupled plasma optic emission spectrometry (ICP-OES) in bottled drinking water samples sold in supermarkets. Linearity, limit of detection (LOD), limit of quantification (LOQ), reproducibility and recovery (%) values were determined. Method validation data results showed that the method is applicable for elemental analysis in bottled drinking water samples. As, Cr, Cu, Fe, Ni, Pb and Zn were not detected in the samples (

Türk Şişelenmiş İçme Sularındaki Elementlerin ICP-OES Kullanılarak Belirlenmesi: Yöntem Validasyonu

Abstract

Ağır metal kirliliği tüm dünyada içme suyunda önemli bir sorun olmuştur. Nüfus artışı ve yetersiz belediye hizmetleri nedeniyle su kirliliğinin artması, insanların şişelenmiş su tüketimini daha fazla tercih etmesine neden olmuştur. Bu nedenle, şişelenmiş içme suyunun mineral bileşiminin belirlenmesi büyük önem taşımaktadır. Bu çalışmada, süpermarketlerde satılan şişelenmiş içme suyu örneklerinde Antimon (Sb), Arsenik (As), Berilyum (Be), Kadmiyum (Cd), Krom (Cr), Kobalt (Co), Bakır (Cu), Demir (Fe), Kurşun (Pb), Lityum (Li), Mangan (Mn), Nikel (Ni), Stronsiyum (Sr) ve Vanadyum (V) indüktif eşleşmiş plazma optik emisyon spektrometresi (ICP-OES) ile analiz edilmiştir. Algılama sınırı (LOD), tayin sınırı (LOQ), tekrarlanabilirlik ve geri kazanım (%) değerleri belirlenmiştir. Metot validasyon verileri, metodun şişelenmiş içme suyu örneklerinde element analizi için uygulanabilir olduğunu göstermiştir. Örneklerde As, Cr, Cu, Fe, Ni, Pb ve Zn tespit edilmemiştir (
