A pH-dependent CT sensitive method for detection of trace Mn in milk by UV-spectrophotometry
(Elsevier, Available )In this study, a new method was developed for the extractive pre-concentration/detection of trace Mn in milk prior to analysis by UV-spectrophotometry. The method is based on the pH-controlled intra-ligand charge transfer ... -
Computational investigation of molecular structures, spectroscopic properties and antitumor-antibacterial activities of some Schiff bases
(ELSEVIER, 2021)Molecular structures, spectroscopic properties (IR, 1 H NMR and 13C NMR, UV-VIS), molecular electrostatic poten tial maps and some molecular properties (ionization energy, electron affinity, energy gap, hardness, electroneg ... -
Novel amide- and imide-co-polymers modified with sulfathiazole as efficient chelator for selective extraction, pre-concentration and determination of trace inorganic antimony (as Sb(III)) from edible vegetable oils by ultrasound assisted-cloud point extraction coupled to micro-volume UV-spectrophotometry
(Elsevier, Available )The study described the synthesis, characterization, and application of newly prepared sulfathiazole-modified amide/imide co-polymers for the extraction of trace Sb(III) from edible vegetable oils. The method was based on ... -

Optimization, spectral characterization, QSAR, and molecular docking analyses of newly designed boron compounds
(2023)In silico analyses of new designed boron compounds were done in detail. In this study, a total of 110 compounds were investigated and optimized at B3LYP-D3/6-31G(d) level in the water. There are two compound groups in ... -
Ultrasonic-assisted cloud point microextraction and spectrophotometric determination of Ponceau 4R in various beverage samples using Non-ionic surfactant PONPE 7.5
(Taylor & Francis, 2021)In the current study, a simple, cheap, and fast analytical procedure, termed ultrasonic-assisted cloud point microextraction (UA-CPME), combined with UV-VIS spectrophotometry, was developed for the pre-concentration and ...
