Cu-electrodeposited gold electrode for the sensitive electrokinetic investigations of nitrate reduction and detection of the nitrate ion in acidic medium

Results in Chemistry, 2023
The electro-catalytic reduction of nitrate ion in acidic media was observed at the Cu-electrodeposited Au surface. The voltammetric analysis represented that the Cu/Au electrode has an enhanced catalytic activity towards nitrate reduction in acidic ...

Synthesis of a terminal Ce(iv) oxo complex by photolysis of a Ce(iii) nitrate complex. [PDF]

, 2017
Reaction of [Ce(NR2)3] (R = SiMe3) with LiNO3 in THF, in the presence of 2,2,2-cryptand, results in the formation of the Ce(iii) "ate" complex, [Li(2,2,2-cryptand)][Ce(κ2-O2NO)(NR2)3] (1) in 38% yield. Photolysis of 1 at 380 nm affords [Li(2,2,2-cryptand)

Elimination of nitrate in secondary effluent of wastewater treatment plants by Fe0 and Pd-Cu/diatomite

Journal of Water Reuse and Desalination, 2018
Because total nitrogen (TN), in which nitrate (NO3–) is dominant in the effluent of most wastewater treatment plants, cannot meet the requirement of Chinese wastewater discharge standard (

Evaluating two concepts for the modelling of intermediates accumulation during biological denitrification in wastewater treatment [PDF]

, 2015
The accumulation of the denitrification intermediates in wastewater treatment systems is highly undesirable, since both nitrite and nitric oxide (NO) are known to be toxic to bacteria, and nitrous oxide (N2O) is a potent greenhouse gas and an ozone ...
