Here, we reported photocatalytic removal of As (III) as well as adsorption of As (III) and As (V) using a novel, porous magnetic Ag/TiO2/Fe3O4@GO nanocomposite which was characterized via FT-IR, XRD, SEM, and TEM. A mathematical model (the central composite design) was used to estimate the relationship between the observed adsorption and our set of variables including initial concentration of arsenic ions, adsorbent dosage, pH, and the contact time. An optimum adsorption capacity of about 91% was observed for As (III) using 20 mg adsorbent with 24 ppm initial concentration of As (III), at pH = 5, within 90 min, and room temperature. Likewise, an optimum adsorption capacity of about 87% was observed for As (V) using 11 mg adsorbent with 17 ppm initial concentration of As (V), at pH = 3, within 30 min, and room temperature. The electrostatic factors between surface charge of nanocomposite and arsenic species were used to explain adsorption behavior of As (III) and As (V) at different conditions. The Langmuir isotherm equations best interpreted the nature of adsorption of As (III) and A (V). It was found during phocatalytic process maximum R% was about 63% for As (III) using 40 mg photocatalyst.","PeriodicalId":7207,"journal":{"name":"Advanced Journal of Chemistry-Section A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74297976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The social and economic health of the modern world depends on sustainable supply of both energy and water. Many areas worldwide suffering from fresh water shortage are becoming increasingly dependent on purification as a highly reliable and non-conventional source of fresh water. Therefore, purification market has greatly expanded in recent decades and expected to continue in the coming years. The integration of renewable energy resources in purification and water purification has become increasingly attractive. This is justified by the fact that areas of fresh water shortages have plenty of solar energy and these technologies can be used due to their low operating and maintenance costs. This review paper discusses the systems that can be used to harness renewable energy sources including, solar collectors, solar ponds, photovoltaics, wind energy and geothermal energy and finally a discussion and conclusion about some distinguished features of each process. Merging of these renewable energy sources with conventional sources has led to optimize the performance of purification plant, less maintenance requirement and reduction in overall cost. It was found that, to choose the best renewable energy source for a purification plant in a particular area, important determinative factors should be considered such as water salinity, area remoteness, plant size, technical infrastructure of the plant, capacity factor, energy consumption and capital cost of the equipment.","PeriodicalId":7207,"journal":{"name":"Advanced Journal of Chemistry-Section A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84561964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We designed novel compounds by changing the pyrazole ring of the molecular structure with its isosteric rings. The main goal of the present study is evaluation of isosterism effect on Zonisamide compound. The studied pyrazole isosters are isothiazole, [c] azaphosphole, [d] azaphosphole, oxaphosphole, thiaphosphole and diphosphole. First, all designed molecular structures were optimized using density functional theory (DFT) computational method by B3LYP/6-311++G(d,p) basis set of theory. All the computations were performed in isolated form at room temperature. Then, making complex of all optimized molecular structures with A-type potassium voltage gated subfamily d member 2 (Kv 4.2) was studied. The ligand-receptor complexes energy data showed all designed molecules except (1H-indazol-3-yl)methanesulfonamide interct with channel weakly. The residues Phe 75, Asp 86, Phe 84, and Phe 74 played main role in making complex with (1H-indazol-3-yl)methanesulfonamide. However, the ADME and biological properties of the designed molecules were carried out using swissADME and FAF-Drugs4 web tools. Based on the ligand-channel complexes docking data and biochemical properties of the compounds, the pyrazole pentet ring is a suitable isostere for isoxazole ring in Zonisamide.","PeriodicalId":7207,"journal":{"name":"Advanced Journal of Chemistry-Section A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74825323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted to investigate the effect of tissue of solid waste on the release of heavy metals from the steel smelting plant. After the investigation at the Khazar steel smelting (KSS) plant in Guilan province, its waste type, source, quantity and quality were characterized. The major wastes generated from the KSS plant were characterized to be the slag, furnace dust, and spent refractories. KSS solid wastes contained heavy metals in varying amounts, with the ranges of 1500-2200, 80–114, 6172-11100, 88-82, 48-29, 56-60, 4-14, 144-370 and 0.9-1.0 mg/kg−1 for Mn, Cu, Zn, Ni, Cr, Co, Cd, Pb and As, respectively. The concentration of the iron was high in these wastes (109900-672000 mg/kg−1). The results confirmed the high concentration of heavy metals except for Arsenic. The TCLP results of the KSS dust and slag showed the almost all the heavy metals concentrations by the leaching test were lower than the detection limits except Fe (524.5-187.6 mg/kg-1) and Mn (14-10.10 mg/kg-1). According to the results, all the wastes generated by the KSS plant were reusable and recyclable.","PeriodicalId":7207,"journal":{"name":"Advanced Journal of Chemistry-Section A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88982861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
