“…It is important to determine trace amounts of iron for public health and environmental protection (Ghosh et al, 2020). Due to its importance in the context of clinical diagnosis and environmental pollution monitoring many methods for the determination of iron have been reported, such as spectrophotometry (Cheng et al, 2021, Nurchi et al, 2021, Totan et al, 2018, Zannat and Ahmed, 2014, inductively coupled plasma-optical emission spectrometry (Didukh-Shadrina et al, 2019, Proch andNiedzielski, 2021) , atomic absorption spectrometry (Gómez-Nieto et al, 2015, Donnici et al, 2016, Kasa and Bakırdere, 2021 ICP-mass spectrometry (Shariff et al, 2018, Laur et al, 2021 , anodic or cathodic stripping voltammetry (Hassler et al, 2013, Węgiel et al, 2017 chromatography (Frankowski, 2012, Kaasalainen et al, 2016 cloud point extraction (Durukan et al, 2011, Gondim et al, 2017, Abou El-Reash et al, 2020, Mortada, 2021 and flow injection analysis (Xue et al, 2020, Koronkiewicz, 2021 . Spectrophotometric methods are widely utilized in many laboratories and countries for everyday work due to their simplicity, availability, low cost, and speed thus in the present work, determination of Fe(II) and Fe(III) as well as total iron as azooxime complex, in aqueous solution using spectrophotomteric method is reported.…”
