Reservoir NO3− pollution and chemical weathering: by dual isotopes of δ15N-NO3−, δ18O-NO3− and geochemical constraints

Environmental Geochemistry and Health, 2022
Reservoir dams alter the nutrient composition and biogeochemical cycle. Thus, dual isotopes of δ18O-NO3- and δ15N-NO-3 and geochemical signatures were employed to study the NO3- pollution and chemical weathering in the Three Gorges Reservoir (TGR), China. This study found that the TGR dam alters the δ15N-NO3- composition and is enriched in the recharge

NO3–⋯NO3– and NO3–⋯π interactions in the crystal of urea nitrate

CrystEngComm, 2007
The geometrical and energy aspects of the NO3−⋯NO3− and NO3−⋯π-system interactions were analyzed in the framework of the charge density investigation in crystalline urea nitrate. The results obtained have revealed that relatively weak anion–anion and anion–π (cation) contacts contribute greatly to the stabilization of the layered structure for this ...

Apparent molar heat capacities and volumes of aqueous electrolytes at 298.15 K: Ca(NO3)2, Co(NO3)2, Cu(NO3)2, Mg(NO3)2, Mn(NO3)2, Ni(NO3)2, and Zn(NO3)2

The Journal of Chemical Thermodynamics, 1979
Abstract We have used a flow calorimeter and a flow densimeter for measurements leading to apparent molar heat capacities and apparent molar volumes of dilute aqueous solutions of Ca(NO 3 ) 2 , Co(NO 3 ) 2 , Cu(NO 3 ) 2 , Mg(NO 3 ) 2 , Mn(NO 3 ) 2 , Ni(NO 3 ) 2 , and Zn(NO 3 ) 2 at 298.15 K.

Low Temperature Thermal Conductivity of (NO3)2Ba, (NO3)2Sr and (NO3)2Pb Single Crystals

1976
In view to investigate the evolution of phonon-phonon interaction in this serie of isomorphous compounds, where anharmonicity is the largest for the Pb nitrate [1], the thermal conductivity K of single crystals has been measured between 1.5 and 300 K (from about ө/60 to 2 ө).The crystallographic cell of these cubic crystals contains 36 atoms [2], so ...

Isomorphism in the (NH4)2Th(NO3)6-K2Th(NO3)6-Rb2Th(NO3)6 system

Russian Journal of Inorganic Chemistry, 2009
Syntheses were developed, and compounds of composition (NH4)2xK2yRb2zTh(NO3)6(x + y + z = 1) were prepared. These compounds were structurally studied using X-ray diffraction and IR spectroscopy. Incomplete miscibility in the solid phase of the title system was found, and the impossibility of existence of a hexanitratothorate complex in the (NH4)2Th(NO3)

Viscosities of ternary systems Y(NO3)3+La(NO3)3+H2O, La(NO3)3+Ce(NO3)3+H2O, La(NO3)3+Nd(NO3)3+H2O and their binary subsystems at different temperatures

Journal of Rare Earths, 2012
Viscosities were measured for the ternary systems Y(NO3)3+La(NO3)3+H2O,La(NO3)3+Ce(NO3)3+H2O,and La(NO3)3+Nd(NO3)3+ H2O and their binary subsystems Y(NO3)3+H2O,La(NO3)3+H2O,Ce(NO3)3+H2O,and Nd(NO3)3+H2O at 293.15,298.15 and 308.15 K.The results were used to test the applicability of simple equations for the viscosity of the mixed solutions.The ...
