Abstract
Cilj istraživanja koje je prikazano u ovom radu je razvoj i vrednovanje kinetičke metode analize N-acetil-L-cistein-etil estera (NACET) uz spektrofotometrijski detektor. Opisana kinetička metoda temelji se na redoks reakciji u kojoj NACET reducira [Cu(BCA)₂]²⁺ kompleks zelene boje u [Cu(BCA)₂]⁺ ljubičasto obojan kompleks čiji se apsorpcijski maksimum bilježi na 562 nm. Optimizirani su parametri kemijske reakcije te je temeljem toga konstruirana krivulja umjeravanja čijom je regresijskom analizom utvrđena jednadžba pravca: y = 5991,8 x + 0,00235. Postignuta je linearnost u području koncentracija od 6,0 x 10⁻⁷ do 1,0 x 10⁻⁴ mol L⁻¹, te su određene granica dokazivanja 1,60 x 10⁻⁷ mol L⁻¹ i granica određivanja 5,45 x 10⁻⁷ mol L⁻¹. Ispitan je i utjecaj pojedinih interferencija na NACET te nije zamijećen nikakav značajan utjecaj na određivanje analita.
Abstract (english)
The main goal of this research is development and validation of kinetic method for the determination of N-Acetylcysteine-ethyl ester (NACET) with spectrophotometric detector. Described kinetic method is based on the redox reaction where NACET reduced [Cu(BCA)₂]²⁺ green complex to the purple [Cu(BCA)₂]⁺ complex with absorption maximum at 562 nm. The parameters of chemical reaction have been optimized and the calibration curve was constructed. Linear dynamic range was from 6,0 x 10⁻⁷ to 1,0 x 10⁻⁴ mol L⁻¹, with equation direction y = 5991,8 x + 0,00235. Limit of detection and limit of quantification were found to be 1,60 x 10⁻⁷ mol L⁻¹ and 5,45 x 10⁻⁷ mol L⁻¹. Impact of certain interferences has been examined and any significant impact on the determination of an analyte has not been noticed.
