A flame atomic absorption spectrophotometric technique was studied for the preconcentration and determination of Co2+ ions in trace amounts after ultrasound enhanced enrichment of its 1-(2-pyridylazo)-2-naphthol (PAN) complexes by cloud point extraction. The Co2+ ions were firstly complexed with PAN molecules at pH 4 and the complex transferred to a surfactant Tergitol NP-7 (TNP-7) rich phase with a very small volume under ultrasound waves. The surfactant rich phase was separated and dissolved by 1 mL, 1.0 M HNO3 in ethanol prior to determination of Co2+ concentration by flame atomic absorption spectrophotometry. The optimization steps of ultrasound interaction time, solution pH and surfactant volumes were achieved by response surface methodology (RSM) which is a combination of statistical approaches. PAN concentration and possible interfering ions were optimized conventionally. The Co2+ ions were extracted only in 150 s at pH 4 quantitatively under optimum conditions (˃95%). The accuracy and validity of developed ultrasound assisted cloud point extraction (UA-CPE) was granted by employing a certified reference material wastewater UME CRM 1204. The technique was applied to wastewater and natural water with satisfactory results.

Ultrason destekli bulutlanma noktası ekstraksiyonu yöntemiyle sulu ortamda bulunan Co (II) iyonlarının hızlı önderiştirilmesi ve tayini

Öz

Eser miktardaki Co2+ iyonlarının 1-(2-Piridilazo)-2-Naftol (PAN) komplekslerinin ultrason destekli bulutlanma noktası ekstraksiyonu ile zenginleştirilmesi ve alevli atomik absorpsiyon spektrofotometri yöntemi ile tayini için bir yöntem geliştirilmiştir. Co2+ iyonları ilk olarak pH 4'te PAN molekülleri ile kompleksleştirildi ve oluşan kompleksultrasonik dalgalar ile küçük hacimli yüzey aktif madde Tergitol NP-7 (TNP-7) bakımından zengin faza aktarıldı. Yüzey aktif madde açısından zengin faz ayrıldıktan sonra 1 mL 1.0 M HNO3 etanolde çözülmüş ve ardından alevli atomik absorpsiyon spektrofotometrisi ile Co2+ konsantrasyonu belirlenmiştir. Ultrason etkileşim süresi, çözelti pH'sı ve yüzey aktif madde hacimlerinin optimizasyon adımları istatistiksel yaklaşımların bir kombinasyonu olan yüzey yanıt yöntemi (RSM) ile gerçekleştirilmiştir. PAN konsantrasyonu ve olası girişim yapan iyonların etkisi geleneksel olarak optimize edilmiştir. Co2+ iyonları sadece 150 saniye içerisinde pH 4'te optimum koşullar altında kantitatif olarak (˃%95) ekstrakte edilmiştir. Geliştirilen ultrason destekli-bulutlanma noktası ekstraksiyonu (UA-CPE)'nin doğruluğu ve geçerliliği, sertifikalı referans malzeme atıksu UME CRM 1204 kullanılarak sağlanmıştır. Yöntem, atık su ve doğal sulara tatmin edici sonuçlarla uygulanmıştır.
