In this study, an efficient and convenient three-component cyclization protocol is presented for the synthesis of xanthene derivatives using a water extract red mud (WERM). Red produced in large quantities as waste aluminum industries, first report to use WERM renewable medium xanthenes. We focused our attention on domino condensation/Michael addition/intramolecular both experimentally density functional theory (DFT) studies, where formation chromenopyrimidines was suppressed simultaneously....
Coordination polymer nanoparticles (CPNs) are a unique class of designed via the self-aggregation metal ion and polydentate ligand. Among them, lanthanide-based CPNs considered to be most promising due their intrinsic luminescent properties, stability in different oxidation states, high coordination flexibility. In present study, cerium-based (Ce-CPNs) have been synthesized using adenosine triphosphate (ATP) as cross-linking A weakly emissive molecular-rotor-type dye, Thioflavin-T (ThT), was...
Thorium (Th) is commonly used in various applications, but its long-term exposure poses health risks, necessitating detection aqueous environments. Traditional methods such as inductively coupled plasma mass spectrometry are sensitive require complex instrumentation. Optical sensors, particularly fluorometry-based methods, simpler, cost-effective, and selective. However, developing effective aggregation-induced emission (AIE) turn-on sensors for Th(IV) requires water-soluble fluorophores...
Manganese dioxide (MnO2) synthesized by solid-state reaction was characterized and sorption of As(III) As(V) on it studied in batch mode using 76As radiotracer. Arsenic removal efficiency ∼98 % the pH range 3–9. Solvent extraction study indicated that >95% arsenic is present as after sorption. A new electrochemical method developed for explaining arsenic–manganese interactions. Cyclic voltammetry chronopotentiometry measurements were carried out which difference interaction with MnO2. X-ray...
Uncertainty, the most important characteristic of an analytical result, has been evaluated using a bottom-up approach during EDXRF determination Pt in alumina. The calibration function spectrometer was derived through bivariate least squares fitting, combination with weighted regression residuals.
Sorption of As(III) and As(V) on manganese dioxide was studied by batch equilibration method using 76As radioactive tracer. Manganese prepared two different methods viz. reacting (a) KMnO4 solution with MnSO4 solution, (b) concentrated hydrochloric acid. characterized zeta potential measurement, surface area thermogravimetry (TG), differential thermal analysis (DTA) X-ray diffraction (XRD) techniques. Point zero charge (PZC) for between pH 3 4. Radioactive tracer (76As) neutron irradiation...
Arsenic in groundwater is a major concern many parts of the world and suitable sorbents are required for removal arsenic from ground water. Removal has been studied using manganese dioxide, synthesized by solid state reaction acetate with potassium permanganate. Manganese dioxide was characterized X-ray diffraction (XRD), zeta potential, surface area, particle size measurements thermal analysis. XRD measurement showed that had α-MnO2 structure. Sorption As(III) As(V) on radiotracer technique...
Gold and silver in dross were determined by energy-dispersive X-ray fluorescence technique. Sample was prepared pressed pellet method using microcrystalline cellulose powder as binder, a of standard additions used for quantification. Lβ gold (11.4 keV) Kβ (24.9 analysis. The measured concentrations 132 ± 8 1181 84 mg kg−1, respectively. results validated instrumental neutron activation analysis t-test indicated that there no significant difference between obtained the two techniques....
Uncertainty, the most important characteristic of an analytical result, has been evaluated using a bottom-up approach during NAA determination Au in copper concentrate. The sampling constant calculated to arrive at representative sample size
Arsenic, which is ubiquitous in nature, was found associated with iron oxides soils and sediments. Our interest to utilize the same mechanism for sorptive removal of arsenic from groundwater. The iron(III) oxides: hematite, goethite, were synthesized, characterized sorption studies [As(III) As(V)] carried out batch mode. For studying evidence interaction between oxide during process sorption, a new electrochemical method developed. Differential pulse voltammetry (DPV) study indicated that...
