“…A pH meter was used to determine the pH (bench pH meter model DM 23 -Digimed, Campo Grande Brazil). The concentration of Fe 3+ was determined using ultraviolet / visible (UV / visible) spectroscopy (GENESYS 20 UV/ VIS Spectrophotometer, Thermo Fisher Scientific Inc., Germany), by reacting potassium thiocyanate in aqueous solution (Tang et al, 2016).…”

Background: There are several lesions of odontogenic and non-odontogenic origin in the oral cavity, such as odontogenic keratocyst, as well as many treatment options for such lesions. In order to reduce recurrence due to conservative treatments and less aesthetic and functional impairment of the patient (radical therapies), Carnoy's solution has been used as an adjuvant to surgery, showing satisfactory results. Its application is not standardized, presenting risks to adjacent tissues. Thus, we characterized the Carnoy's solution with different viscosity agents to enhance its applicability. Material and Methods: All solutions prepared (Carnoy with and without chloroform) were added with viscosity agent: ethyl cellulose, propylene glycol, and glycerol totaling eight solutions. The pharmacological characterization of the solutions was performed by determining the mass density and relative density (using a clean and dry pycnometer), pH (using pH meter), and concentration of Fe 3+ (using ultraviolet/visible spectroscopy). The analyses of the inorganic components were determined by Raman micro spectrometry. Data were analyzed with statistical program BIOESTAT 5.3. Results: Solutions with ethyl cellulose were discarded due to precipitate formation and suspension of the viscosity agent. In the other solutions, viscosity increase (propylene glycol solutions) and acidic pH were observed mainly in the glycerol group. The ferric chloride characterized as a hemostatic agent had its concentration increased with the use of thickening agents, theoretically favoring its action. Conclusion: The similarity of the propylene glycol and glycerol molecules justifies the Raman spectra of these substances to be similar and the difficulty in obtaining a "fingerprint".

“…Among the heavy metals, Fe and Cu are the first and second most widely used industrial metals worldwide (3). Fe 3+ plays a significant role in various metabolic processes including oxygen transport, enzyme catalysis, DNA and RNA synthesis, and hemoglobin synthesis (4). Although Fe 3+ is necessary for living organisms at low concentrations, biological disorders such as Alzheimer's, Parkinson's, and Huntington's diseases and, renal failure are seen with uptake of Fe 3+ at high concentrations (5).…”

Herein, two novel ion-selective electrodes are reported for simultaneous potentiometric determination of Fe 3+ and Cu 2+ ions. The liquid polymeric membrane components were optimized and the resulting pencil graphite electrodes gave Nernstian slopes of 20.7 mV/decade and 31.2 mV/decade with lower detection of limit of 1×10 -6 mol L -1 and 2×10 -6 mol L -1 , and wide pH range of 1.5-3.5 and 2.0-4.7 for Fe 3+ and Cu 2+ ions, respectively. The electrodes exhibited very fast response time (<6 s). In addition, the electrodes exhibited high selectivity for Fe 3+ and Cu 2+ ions against different cations, which were tested by matched potential method. The sensing platform using the optimized electrodes were integrated with the Internet of Things concept are suitable for simultaneous monitoring of Fe 3+ and Cu 2+ in real samples with high accuracy and precision.
