Analytical reagent sodium tungstate is referred to as sodium tungstate that meets the purity standards, which ensures the scientific precision and reliability of chemical analysis, chemical reaction or physical testing.
Coprecipitation Separation of Trace Impurities in Sodium Tungstate and Determination by ICP-AES
Using lanthanum hydroxide as co-precipitant, trace metal impurity elements (calcium, cadmium, zinc, iron, manganese, nickel, and zinc) in sodium tungstate were coprecipitated, separated, enriched, and measured by ICP-AES (Inductively Coupled Plasma-Atomic Emission Spectrometry).
Analytical reagent means the sodium tungstate is reagent-grade. In commercial or laboratory preparations, reagent-grade designates chemical substances meeting standards of purity that ensure the scientific precision and reliability of chemical analysis, chemical reactions or physical testing. Purity standards for reagents are set by organizations such as ASTM International or the American Chemical Society. While laboratory products which are less pure, but still useful and economical for undemanding work, may be designated as technical, practical, or crude grade to distinguish them from reagent versions.
