Rhenate of ammonia, rhenate of potassium, oxide of calcium, oxide of molybdenum, rich-manganese slag, spiegeleisen(containing manganese), lime, lead sulfide, electrode paste.
So long as their balance remains undisturbed, the oxygenated and hydrogen sulfide–saturated waters stay separated, and their interface, known as the chemocline, is stable.
Ankerite microclinite, a special type of rock, is closely related to the ore-forming process of massive sulfide deposits in the East Liaoning Proterozoic rift.
Based on these results and the ESI-MS data, the mechanism of sulfoxidation was proposed to be intramolecular nucleophilic oxygen transfer to a coordinated sulfide.
The results show experiment have a higher removal rate and the last oxidize product of hydrothion and mercaptan is condensed state sulfide, could not be sulfur dioxide.
The deionizing and deoxidizing water is required by the methylene blue spectrophotometric method in the new national standard to analyze sulfide in water and waste water.
Which indubitably indicate that the bismuthous sulfide can only dissolve in halogen acid except hydrofluoric acid, the mixed solution of dilute sulfuric acid and alkali halide.
Red algae cystocarp was found for the first time and the discovery of the close relationship between algae cystocarp and metal sulfides has supplied the evidence for biomineralization.
It is studied further that the dissolubility of the bismuthous sulfide in the solutions of the non-oxidative strong acid through the experiment by means of chemical thermodynamics.
In addition, non-coated paper in high-humidity environment of sulfide, chemical pulp and fill applicatron dottle out acid melted, making of gold and silver monlchamus nigrescent who lose their luster.
