Hydrogen sulfide and organic compounds removal in municipal wastewater using ferrate (VI) and ultraviolet radiation

 Background: In this study, ferrate (VI) and ultraviolet (UV) radiation were employed to remove hydrogen sulfide from municipal wastewater resulting in a reduction in chemical oxygen demand (COD). Although ferrate (VI) and UV have been used individually for the removal of a few pollutants from urban and industrial wastewater, there exists no study to investigate the effectiveness of si...

synthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...

Removal of Emulsified and Dissolved Traces of Organic Compounds from Industrial Wastewaters Using Natural and Synthesized (NaA and NaM) Zeolites

The main object of this study was to compare the natural and synthetic( NaA and NaM) zeolites as absorbents in removing emulsified and dissolved traces of organic compounds, which appear in the wastewater of  power plants, refinery and petrochemical complexes.  The specific objectives of the work was: a) to select the best species that have the highest amount of absorption; b) to measure th...

Determination of Trace Metals, Volatile Organic Compounds, and Other Water Standards in WMU Drinking Water

Potentiometric Determination of Acidity Constants of Some Synthesized Organic Compounds in Organic-Water Media

The acidity constants of some synthesized protonated pyrazolo quinazoline compounds were determined potentiometrically at ionic strength of 0.1 M in DMF: water (60:40 v/v) system at different temperatures (298.15 K to 318.15 K). The pKa values have been found to increase with increasing electron-donating nature of substitutions. Some thermodynamics parameters such as enthalpy (ΔH°), Gibb’s free...
