Amaç & Hipotez:Objectives: The electro-oxidation behavior of the non-steroidal anti-inflammatory drug tenoxicam (TX) was studied on multiwalled carbon nanotube(MWCNT)-modified glassy carbon electrode (GCE) by cyclic voltammetry, differential pulse voltammetry (DPV), and square wave voltammetry(SWV).Materials and Methods: The GCE was modified with MWCNT for sensitive determination of TX by voltammetric methods.Results: The current peaks for TX occurred at around 0.520 V for DPV and 0.570 V for SWV when the potential was scanned in the positivedirection.
📊
Temel Bulgular & Veri:The oxidation process of TX showed irreversible and diffusion-controlled behavior.

Abstract

Amaç: Non-steroidal antienflamatuvar ilaç etken maddesi tenoksikamın (TX) elektro-oksidasyon davranışı çok duvarlı karbon nanotüple (MWCNT) modifiye edilmiş camsı karbon elektrot (GCE) ile dönüşümlü voltametri, diferansiyel puls voltametri (DPV) ve kare dalga voltametri (SWV) ile çalışılmıştır. Gereç ve Yöntemler: GCE, TX’in voltametrik metodlarla hassas tayini için MWCNT ile modifiye edilmiştir. Bulgular: Potansiyel pozitif yönde tarandığında TX’in pik akımı 0.520 V civarında DPV ile, 0.570 V civarında SWV ile oluşmuştur. TX’in oksidasyon prosesi tersinmez ve diffüzyon kontrollü davranış göstermiştir. DPV ve SWV için doğrusal cevaplar sırasıyla 2×10-7-1×10-5 M, 1.43×10-9 M yakalama alt sınırı (LOD) ile, 8×10-9-8×10-6 M, 9.97×10-10 M LOD ile 1 M asetat tamponu pH 5.5 içinde elde edilmiştir. Sonuç: Tamamen valide edilmiş DPV ve SWV başarılı bir şekilde TX’in farmasötik dozaj formundan miktar tayini için uygulanmış ve memnun edici sonuçlar elde edilmiştir.
