Ir 470

The solution of Amoxi-TPP-AuNPs and AuNPs was centrifuged at 12,000× g for 15 min. The unattached biological components from the surface of the nanoparticles were removed by washing the residue from earlier products with bi-distilled water. A spectrometer (Shimadzu IR-470, Tokyo, Japan) was used to quantify the FT-IR in the 4000–400 cm⁻¹ region using the powder of the extract of J. excelsa leaves, AuNPs, TPP-AuNPs, and Amoxi-TPP-AuNPs [24 (link)]. In order to create discs, 100 mg of grade KBr was mixed with 100 mg of hydraulic pressure after the sample had been desiccated at 100 mg. The peak heights were represented by the FT-IR peak wavenumbers (cm⁻¹) that were found.

FT-IR was determined using a spectrometer (Shimadzu IR-470, Tokyo, Japan) over 4000–500 cm⁻¹ [22 (link)].

All melting points reported for the monomers, pre-monomers and model compound are uncorrected and determined on a Gallen-kamp Melting Point apparatus with a digital thermometer type MFB-595-010M. Elemental analyses were estimated by an Elemental Analyses system GmbH, VARIOEL, V_2.3 July 1998 CHNS Mode. IR spectra were determined on IR-470, Infrared spectrophotometer, Shimadzu using the KBr pellet technique. Room temperature ¹H-NMR spectra were carried out on a varian EM-390-NMR (90 MHz) spectrometer and a GNM-LA 400-MHz NMR spectrophotometer using DMSO or CDCl₃ as deuterated solvents and in the presence of TMS as an internal reference. Mass spectra were investigated on a Jeol JMS600 mass spectrometer. I-V method (two electrodes composed onto fabricated GCE) was measured for toxic arsenic ions for PAAP/GCE by using Keithley-Electrometer from USA.
