Abstract

Bu
makalede, nikel tayini için,
herhangi bir ön deriştirme işlemi uygulamadan, pH 5,5 (5-6) 'da 2,3,4,6^/-tetrahidroksi-3^/-sülfoazobenzen
(THSA) ile şelat oluşturarak seçici ve duyarlı bir spektrofotometrik yöntem
önerilmiştir. Metal ligand oranı 1: 1 olan kompleksin, 485 nm'de, molar
absorplama katsayısı 1,60 ×10⁴ L mol⁻¹ cm⁻¹
'dir. Kompleks bileşik 3 saat kararlılığını korumaktadır. Ayrıca, 50 °C’ye kadar bozulmadan kalır. Geliştirilen yöntem
0,040-2,348 µg mL⁻¹ Ni (II) tayin aralığında Beer’in kanununa uyar.
Toprak alkali elementler, alkalin elementler, nadir toprak elementler,
halojenürler, fosfatlar, askorbik asit ve katyonlar nikel tayini engellemez. Önerilen
yöntem hızlı ve basittir ve nikel tayini için sertifikalı alaşımlara ve çevre
suyu örneklerine kolayca uygulanabilir.

Spectrophotometric Determination of Trace Amount of Nickel in Real Samples by Using Hydroxyazo Compound

Abstract

In this
article, a selective and sensitive spectrophotometric by chelating with 2,3,4,6^/-tetrahydroxy-3^/-sulfoazobenzene
(THSA) at pH 5.5 (5-6) without applying any preconcentration process for nickel
determination method is proposed. A
selective and
sensitive spectrophotometric method has been proposed for the determination of
nickel by forming chelate at pH 5.5 (5-6) with 2,3,4,6^/-tetrahydroxy-3^/-sulfoazobenzene
(THSA). Molar absorptivity of the complex having metal ligand ratio of 1:1 is
1.60 × 10⁴ L mol⁻¹ cm⁻¹ at 485 nm. The complex
compound is stable for 3 hours. Furthermore, it is stable up to 50 ° C. The
developed method obeys Beer’s law for 0.040-2.348 µg mL⁻¹ Ni(II).
Earth alkaline elements, alkaline elements, rare earth elements, halides,
phosphates, ascorbic acid and cations do not interfere nickel determination.
The proposed method is rapid and simple, and it can be easily applied on
certificated alloys and environmental water samples for determining nickel.
