Certain structural, energetic, quantum chemical and spectral data have been obtained for them and discussed. The both methods of calculations generally produce parallel results.</p> Lemi Türker Copyright (c) 2021-04-19 2021-04-19 6 1 1 14 10.34198/ejcs.6121.114 The Chemistry of van de Moer Test for Cytisine https://earthlinepublishers.com/index.php/ejcs/article/view/330 <p>Cytisine is an alkaloid with biological activity that is used as medication for smoking cessation treatment. It is a quinolizidine derivative, one ring being 2-pyridinone, and there is a third cycle, a disubstituted piperidine. Thus, the analytical chemistry of this compound is relevant. In this communication we provide the chemistry involved in the spot test for cytisine identification by means of ferric chloride/hydrogen peroxide. The electron flow, step by step, is given from the alkaloid to the final colored products. The sequence is based on the chemical properties of the substrate and reagents, disclosing the series of reactions occurring in this assay. The process is in accordance with the experimental results. We also give the mechanism of cytisine degradation, from a quinolizidine system to 6,8-dimethyl quinoline, which involves an interesting rearrangement.</p> Francisco Sánchez-Viesca Reina Gómez Copyright (c) 2021-04-21 2021-04-21 6 1 15 22 10.34198/ejcs.6121.1522 DFT Treatment of ANTA and Some of its Tautomers https://earthlinepublishers.com/index.php/ejcs/article/view/334 <p>An insensitive explosive material, ANTA, and some of its prototropic tautomers have been considered within the constraints of density functional theory at the levels of B3LYP/6-311++G(d,p) and B3LYP/cc-PVTZ (partly). Various energetic, quantum chemical and spectral properties have been obtained and discussed. The NICS(0) values have been obtained and contemplated on them.</p> Lemi Türker Copyright (c) 2021-04-27 2021-04-27 6 1 23 36 10.34198/ejcs.6121.2336 Enhanced Electrochemical Treatment of Phenanthrene-polluted Soil using Microbial Fuel Cells https://earthlinepublishers.com/index.php/ejcs/article/view/337 <p>In this study, tubular microbial fuel cells (MFCs) were inserted into phenanthrene-contaminated water-logged soil in order to evaluate their treatment efficiency and overall system performance within 60 days’ incubation period. At day 10, phenanthrene degradation rates were found to decrease with increasing distance from the anodes from 50-55 % at 2 cm to 38-40 % at 8 cm. Bromate (used as a catholyte) removal in both MFCs was about 80-95 % on average which is significantly higher than the open circuit controls (15-40 %) over the 60day period. Total chemical oxygen demand removal (72.8 %) in MFCs amended with surfactants was significantly higher than MFCs without surfactant (20 %). This suggests that surfactant addition may have enhanced bioavailability of not only phenanthrene, but other organic matter present in the soil. The outcomes of this work has demonstrated the simultaneous removal of phenanthrene (86%) and bromate (95%) coupled with concomitant bioelectricity generation (about 4.69 mWm<sup>-2</sup>) using MFC systems within a radius of influence (ROI) up to 8 cm. MFC technology may be used for <em>in situ </em>decontamination of soils due to its potential detoxification capacity and could be deployed directly as a prototype-MFC design in field applications.</p> Oluwaseun Adelaja Tajalli Keshavarz Godfrey Kyazze Copyright (c) 2021-05-04 2021-05-04 6 1 37 63 10.34198/ejcs.6121.3763
