Dissolved oxygen microelectrode sensors for analysis of trace amounts of dissolved oxygen

Journal of the College of Basic Education, 2022
يصف هذا البحث تطوير مستشعر قطب كهربائي جديد (MES) للقياسات الموضعية للأكسجين المذاب (DO) باستخدام تقنيات التصنيع الدقيق. تم استخدام تقنية الحفر الديناميكي لتصنيع مجسات استشعار بطول 20 مم وشحذها إلى أبعاد ميكرومتر. استخدمت المستشعرات قطبًا كهربائيًا لاستشعار الذهب داخل تجويف مُصنع عند طرف كل قطب كهربي صغير.

Cerium anomaly as a tracer for paleo-oceanic redox conditions: A thermodynamics-based Ce oxidation modeling approach

Frontiers in Earth Science, 2022
Reconstructing redox conditions in the paleo-ocean is essential to understand the Earth’s biogeochemical evolution. Cerium (Ce) anomaly in marine sediments has been used to distinguish oxic versus anoxic depositional environments in the Paleo-ocean ...

Dissolved oxygen determination in sewers using flow hydraulic parameters as part of a physical-biological simulation model

Journal of Hydroinformatics, 2022
This paper aims to develop a model for calculating the hydraulic and water quality parameters of wastewater within sewers. Information from the wastewater collection network and the transmission line in Birjand were used to verify the model performance ...

Benthic fluxes of dissolved organic nitrogen in the Lower St. Lawrence Estuary and implications for selective organic matter degradation [PDF]

, 2013
The distribution of dissolved organic nitrogen (DON) and carbon (DOC) in sediment porewaters was determined at nine locations along the St. Lawrence estuary and in the gulf of St. Lawrence. In a previous manuscript (Alkhatib et al., 2012a), we have shown

The dependence of the consumption of dissolved oxygen on lake morphology in ice covered lakes

Hydrology Research, 2020
The consumption of oxygen in ice-covered lakes is analyzed and related to biological oxygen demand and sediment oxygen demand. An approach for computing dissolved oxygen concentration is suggested assuming horizontally mixed waters and negligable ...
