Authors: Aljeboree Aseel M , Noor Alshirifi Abbas 
Published: October 2019

Abstract
Amoxicillin (AMX) is a semi-synthetic β-lactam antibiotic belonging to the group of penicillins. When ingested, it is partially (about 80–90%) excreted as chemically unchanged via faeces and urine into the domestic sewage and thence discharged to the wastewater treatment plants, which subsequently, removing this substance from the aqueous solution is important. Therefore, the aim of current study was to determine the effects of different optimum conditions of the oxidative coupling calorimetric methods for the quantitative determinations of Amoxicillin. Methods: Amoxicillin was determined via using colorimetric spectrophotometric method in the alkali medium and adding 4-aminoantipyrine to give a panic-colored chromophore which is spectrophotometrically estimated at 509 nm, at room temperature in the presence of ferricyanide ion. Beer’s law is observed in a concentration range 5-100 mgL−1 and linearity(r2=0.9994) according to the proposed conditions. Results: The best concentration of 4AAP was 0.3gm/100 ml and that of the oxidant was 0.3gm/100 ml at the same order. Conclusion: the best results of reagent 4AAP is 0.3g/ml to give high stability indeed highly more absorptivity to enhance measurements and reduce error.

Abstract
The azo reagent 3-((benzothiazol-2-diazenylnaphthalene-2,7-diol] was synthesized and characterized by FT-IR, 1H-NMR and 13CNMR spectral techniques. The electrochemical behavior of the azo reagent and its complex with Fe (III) has been studied at glassy carbon disk GCE electrode in different supporting electrolyte at concentration (1M) and scan rate (100mvs-1). Spectrophotometric determination of Iron (III ) is based on the formation of a 2:1 complex with above reagent. The complex has λmax at (576) nm and εmax of( 1.6451*104)L.mol-1.cm-1. A linear correlation (0.1 – 4.0 μg. ml-1) was found between absorbance at λmax and concentration. The effect of diverse ions on the determination of Iron (III) to investigate the selectivity of the method were also studied. The stability constant of the product was (3.098*108 ).

Published: October 2019

Abstract
This research highlights the synthesis of novel organic molecule that is 5-methoxybenzimidazolthiomethanol (MBITM). This molecule is synthesized via the reaction of 5-Methoxy-2-mercaptobenzimidazole with formaldehyde in ethanol. This resulting molecule was characterized via Fourier-transform infrared spectroscopy (FTIR), proton-nuclear magnetic resonance (1H-NMR) and elemental analysis (CHN). Furthermore, MBITM is used as a base compound for preparation of one novel nano material by mixing it with silver nanoparticles (Ag NPs) that prepared by green method using Zizyphus spina christi L (Seder) leaf, via a simple chemical reaction. The resulting Ag anchored MBITM (Ag-MBITM) was characterized by FTIR, X-ray diffraction (XRD) and Energy-dispersive X-ray spectroscopy (EDX) measurements. All these characterization measurements establish that a stable MBITM can be electrostatically retained on the surfaces of the Ag NPs. MBITM, Ag NPs and their nano derivative were screened for their antibacterial activity against both types of bacteria Gram-positive (S. aureus) and Gram-negative (E. Coli). In general, E-Coli and S. aureus were exposed to be significantly inhibited by all these three compounds but with different inhibition levels. Besides, the study of the biological activity was adopted for the purpose of conducting a comparative study between the raw materials (Ag NPs, MBITM) and the nanomaterial (Ag-MBITM) resulting from their reaction. The results showed that nanosilver-organic hybrid had effectively developed the antibacterial ability for both starting compounds. It has also been observed that this hybrid has been particularly effective with respect to the gram-positive bacteria.
