“…Due to the characteristics of the adsorbent surface affecting the process, which is the number of active sites and the large surface area 11 . Tn this study, a nanocomposite of the type spinel, CuCo2O4, was synthesized because it is stable in the removal processes 12 . Fuchsin basic (BF) dye, known as Magenta II, has the chemical formula C20H20ClN3 and is a mixture of the three dyes Rosaniline, Pararosaniline, and Magenta II 13 .…”

This study involves the synthesis of CuCo2O4 spinel-type nanocomposite. This material was synthesized using the co-precipitation method and characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-rays Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), and Atomic Force Microscopy (AFM). The activity of the synthesized materials was investigated by following removing basic fuchsine (BF) dye from its aqueous solution by adsorption. Different adsorption parameters were conducted involving the dose of adsorbent surface, time of adsorption, pH of the medium, and temperature. The optimum removal efficiency was around 97 % at contact time 5 minutes, 0.005g of dose the surface adsorbent, pH = 8 and 50 mg. L-1 concentration of dye. Thermodynamic parameters for the adsorption of this dye over the prepared materials were also conducted such as free energy (∆G) negative. While enthalpy (∆H) positive which indicates the adsorption was spontaneous and endothermic, also entropy (∆S) was positive shows the affinity of the adsorbent towards the adsorbate.

“…[12][13][14][15][16][17] FAAS, being easy to use and costeffective, is prevalent in laboratories. [18][19][20] However, detecting trace analytes with FAAS is hindered by higher quantification limits and matrix effects. 21,22 Consequently, a separation-preconcentration approach enhancing sensitivity and selectivity is crucial before employing FAAS.…”

MgAl2O4@MoSe2 nanocomposite was used to separate-preconcentrate bismuth ions for micro solid phase extraction (µ-SPE). FT-IR, SEM, XRD, SEM-Mapping and SEM-EDX were used to find out about the functional groups, surface morphology, surface area, elemental composition, and crystalline structure of MgAl2O4@MoSe2. Analytical parameters, such as pH, adsorbent dose, sample volume, eluent concentration and volume, vortex time, and matrix effect, were optimized to get the best recovery values. Under optimized experimental conditions and by using FAAS measurements, analytical parameters were calculated, such as the limit of detection, the limit of quantification, the preconcentration factor, the enhancement factor (EF), the relative standard deviation, the sample volume, and the eluent volume as 0.012 μg L -1 , 0.04 μg L -1 , 10, 8.69, 5.5, 30 mL, and 3.0 mL, respectively. The validation of the presented procedure was checked by the analysis of certified reference materials and the addition-recovery test to real samples. The presented method was applied for the determination of bismuth contents of natural water, food, and cosmetic products. Two certified reference materials (CRMs) (NCS ZC 73028 Rice and NCS ZC 73036 Green tea) were used for the validation of the presented method.
