Vertex 70 ftir ft raman

The formed Nano ZT and Nano ZT/Vit B 12 were characterized by XRD (PANalytical Empyean, Sweden). An accelerating voltage of 40 KV was applied, using scan angle ranging from 5 to 80°, a scan step of 0.05°, and a 30 mA current. A Bruker devise (vertex 70 FTIR-FT Raman) was used to investigate the vibration of the chemical bonds. A Germany spectrophotometer (serial number 1341) screening the frequency range of 400–4000 cm⁻¹ was applied using a potassium bromide disc. The surface morphology of the prepared materials was investigated using a scanning electron microscope (SEM), Germany. EDX (Quanta FEG250, Germany) was performed to determine the elemental composition in the synthesized materials. The BET specific surface area, pore volume and pore size distribution of the Nano ZT were estimated by N₂ adsorption–desorption method by an automatic surface analyzer (TriStar II 3020, Micrometrics, USA). High-resolution transmission electron microscopy (HRTEM) (JEOL-JEM 2100) was applied to determine the microstructures of the produced materials. XRF analysis was performed on the natural Nano ZT to confirm the structure using XRF-ARL-9900. The partial size and zeta potential were investigated [20 (link)].

The prepared nano-HAP and nano-HAP/Vit B12 were evaluated using XRD (PANalytical Empyrean, Malvern, United Kingdom) using a scan angle range of 5 to 80 degrees, a scan step of 0.05 degrees, a current of 30 mA, and a 40 KV accelerating voltage. FTIR was acquired using a Bruker vertex 70 FTIR-FT Raman. Scanning electron microscopy and EDX analysis for morphological examination and ascertaining elemental composition were performed using SEM-EDX Quanta FEG250 (Elecmi, Zaragoza, Spain). An automatic surface analyzer employing the N₂ adsorption–desorption method was used to assess the BET-specific surface area, pore volume, and pore size distribution of nano-HAP and nano-HAP/Vit B₁₂ (TriStar II 3020, Micromeritics, Norcross, GA, USA). For the determination of microstructures, HRTEM (high-resolution transmission electron microscopy) (JEOL-JEM 2100, Akishima, Tokyo, Japan) was used.

The synthesized LDH was characterized by XRD (PANalytical Empyean, Sweden). The accelerating voltage used was 40 kV, and 30 mA current (ranging from 5 to 60° scan angle and a scan step of 0.05°). Bruker (vertex 70 FTIR-FT Raman), Germany FTIR spectrophotometry (serial number 1341) covering a frequency range of 400—4000 cm⁻¹ was used for FTIR measurements. Samples were applied using KBr discs. Zeta potential and hydrodynamic particle size were investigated by the nanozeta sizer (Malvern Instruments Ltd, United Kingdom). The procedure of sample preparation for zeta potential measurements was as explained in our previous work²¹ . The microstructures of the prepared LDH were determined using high-resolution transmission electron microscopy (HRTEM, JEOL, JEM-2100, Tokyo, Japan).
