“…MBT is also known as a poorly biodegradable pollutant that has potentially mutagenic, carcinogenic and allergenic influences on humans and can easily enter into the environment. Till now, many studies have been developed for the determination of MBT because of its manifold usages and toxic nature, but no attempts have been made to MBT sensing using AgNPs (Parham and Khoshnam, 2013;Jing et al, 2013).…”

“…In this step, the -SH group of MPA reacted with the CuONPs surface as can be seen in the literature [44,45], thus leaving free -COOH groups and a negative charge on the oxide surface when the pH value was between 5.00-8.00, increasing in this way, the selectivity of the PC. After that, 5 mL of mesoporous shuttle-like…”

AbstractA novel method for preconcentration and electrochemical detection of zinterol in bovine urine samples was developed. In order to improve the limit of detection, the surface of a screenprinted carbon electrode was modified with electrodeposited metal copper nanoparticles. The experimental electrodeposition optimization was performed using a central composite design (CCD), involving the variables: precursor concentration, potential and time applied. Copper nanoparticles were characterized by transmission electron microscopy, scanning electron microscopy, cyclic voltammetry, and energy dispersive X-ray spectroscopy. Mesoporous 2 shuttle-like copper oxide nanoparticles were used for the preconcentration step to avoid interferences with many compounds present in the sample matrix. The optimal working conditions for the preconcentration approach were found by means of both two-level fractional factorial and CCD designs. The obtained enhancement factor for a sample volume of 30 mL was 35 fold. The calibration curve showed linearity between 0.5-45 ng mL -1 and the limit of detection was 0.16 ng mL -1 . The intra and inter assay coefficients of variability were below 4% and 5%; respectively.

The geometrical structure of 5-amino-2-mercaptobenzimidazole (5A2MBI) was done and the corresponding structural parameters were calculated on the basis of the calculation by using B3LYP/6-311G (d, p) level, The FT-IR and Raman spectra of 5A2MBI were recorded in the solid phase, the results are compared with the theoretical spectrum calculated by using B3LYP/6-311G (d, p) level, our calculated results are in good agreement with the experimental values. The assignments of the vibrational spectra on 5A2MBI are well resolved and accurately assigned on the basis of the results of the potential energy distribution (PED) which was carried out by the VEDA 4 program. Besides, The Frontier molecular orbitals, UV-Vis spectrum were investigated using theoretical calculations.
