Yellow Matters Improving the remote sensing of Coloured Dissolved Organic Matter in inland freshwaters
De hoeveelheid opgeloste organische stoffen (Dissolved Organic Matter DOM) in oppervlaktewater, en de samenstelling ervan, is een belangrijke graadmeter van de fysisch-chemische waterkwaliteit. Dit proefschrift beschrijft een drietal mogelijkheden om de concentratie van gekleurde opgeloste organische stoffen (Coloured Dissolved Organic Matter CDOM) in natuurlijke Nederlandse oppervlaktewateren ...
متن کاملsynthesis 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 ...
15 صفحه اولUse of Dissolved Organic Carbon to Biostimulate Rapid Rhizodegradation of Perchlorate in Soil
Contamination of freshwater resources, fresh produce and some processed foods by perchlorate (ClO4 -) is a growing problem in the United States. The anion perchlorate is a naturally occurring as well as an anthropogenic chemical which occurs as salts of ammonium, sodium and potassium. The natural sources of perchlorate include Chilean caliche which is mined for use as a natural source of NaNO3 ...
متن کاملDetermination of total dissolved inorganic carbon in freshwaters by reagent-free ion chromatography.
Studies of inorganic carbon cycle in natural waters provide important information on the biological productivity and buffer capacity. Determination of total inorganic carbon, alkalinity and dissolved carbon dioxide gives an indication of the balance between photosynthesis and respiration by biota, both within the water column and sediments, and carbon dioxide transfers from the water column to ...
متن کاملA Rapid Automated System for the Analysis of Dissolved Total Organic Nitrogen in Aqueous Solutions
-An automated system for the analysis of dissolved organic nitrogen has been developed and applied to natural waters. It is based on subjecting sample to u.v. irradiation followed by a heterogeneous reduction of the nitrogen containing irradiation products to ammonia which is detected by an ammonia gas sensing probe. Quantitative recoveries of different organic nitrogen compounds common to natu...
