Using the process of ion exchange of removing P, Si, As, Mo to produce high purity APT, sulfidizing agent including Na 2S, NaHS, H 2S has been used to prepare thiomolybdate from sodium tungstate solution, and then to separate thiomolybdate from tungsten.

Impregnation parameters included PH,concentration of the ammonium thiomolybdate solution, impregnation temperature and time,as well as the state of activated carbon before impregnation.

he drying process of ammonium thiomolybdate supported on activated carbon was studied.

Nickel oxythiomolybdate (NiMoO2S2) nanoparticles with an average size of 15 nm were synthesized in the microemulsion system of sodium dodecyl-sulphate (SDS)/isopentanol/cyclohexanene/water.

Determination of SeO_2 in industrial selenium dioxide by sodium hyposulfite titration;

This paper mainly studied on the influence of the deoxidant(sodium hyposulfite) upon Xanthan gum thermal stability,and the results showed that the viscosity reduction degree is decreased and the viscosity stability of Xanthan gum solution can be obviously improved which makes thermal stability enhance by 1.

After comparison,sodium hyposulfite is the preferred absorbent,which the resultant has no influence on the environment with sodium hyposulfite over absorbed dose.

Study on metabolic mechanisms of sodium thiosulfate by Thiobacillus Ferrooxidans and Thiobacillus Thiooxidans;

Study on preparatin of sodium thiosulfate by sulfur black wastewater

According to the reducibility of sodium thiosulfate,the interference of sulfite is eliminated by formaldehyde and sodium thiosulfate is determined by indirect iodimetry with addition of excessive iodine.
