Characterization of natural Yemeni zeolites as powder sorbents for ammonium valorization from domestic waste water streams using high rate activated sludge processes [PDF]
, 2018 BACKGROUND In this study three natural Yemeni zeolites (NZ1, NZ2 and NZ3) having major minerals such as clinoptilolite and mordenite, were evaluated as low cost sorbents for the removal and recovery of ammonium ions.

Crystal structure of catena-poly[diammonium [di-μ-oxalato-cuprate(II)]]
Acta Crystallographica Section E: Crystallographic Communications, 2016 The structure of the title compound, {(NH4)2[Cu(C2O4)2]}n, at 100 K has monoclinic (P21/c) symmetry with the CuII atom on an inversion center. The compound has a polymeric structure due to long Cu...O interactions which create [Cu(C2O4)2] chains along ...

Soluble species in aerosol and snow and their relationship at Glacier 1, Tien Shan, China [PDF]
, 1998 Simultaneous sampling of aerosol (n = 20) and snow (n = 114) was made at Glacier 1, Tien Shan, between May 19 and June 29, 1996. Similar temporal patterns of some major ion (calcium, magnesium, potassium, sodium, chloride, and sulfate) concentrations ...

MolbankAmmonium oxathioamidate (1) was synthesised by the reaction between O-ethyl-thioxamate (oxalic acid-1-amide-2-O-ethyl ester) and ammonium hydrogen carbonate in water solution. Compound 1 was fully characterised by both microanalytical (elemental analysis, melting point determination) and spectroscopic means (FT-IR and NMR spectroscopy).

Nutrient optimization in bioleaching: are we overdosing?
Frontiers in MicrobiologyThe general trend in biomining (i.e., bioleaching and biooxidation) is the use of media with high concentrations of the nutrients (nitrogen as ammonium, phosphorous as phosphate, and K), which are considered to be essential for microbial growth.
