In this paper, multivariate calibration methods of partial least squares (PLS) and principle component regression (PCR) were investigated in simultaneously determination of hydrazine (HZ) and acetylhydrazine (AHZ). The aforementioned methods are based on formation of the silver nanoparticles (AgNPs) from the reaction of HZ and AHZ with Ag+ ions as oxidizing agent in the presence of citrate ions...
Objective: To develop an ultraperformance liquid chromatography (AcquityTM UPLC) method for simple, fast, accurate and simultaneous determination of nitrite and nitrate ions as stable forms of nitric oxide (NO) production in rat plasma. Methods: The ion-pairing AcquityTM UPLC method with reverse phase BEH C18 column was used along with photodiode array (PDA) UV-Vis detector to separate and dete...
In this study, 2-aminobenzoic acid (ABA) has been used as complexing ligand for simultaneousdetermination of metal ions by adsorptive cathodic stripping voltammetry (AdCSV), for the firsttime. Thus, a selective and sensitive procedure was presented for simultaneous determination oflead, cadmium and nickel using ABA and differential pulse-adsorptive cathodic strippingvolt...
The net analyte signal standard addition method was used for simultaneous spectrophotometric determination of sertraline and fluoxetine in pharmaceutical preparations. The method combines the advantages of the standard addition method with the net analyte signal concept to enable the extraction of information about an analyte from the spectra of multi-component mixtures. This method uses full s...
