Determination of sulfur sulfide |
| abstract |
PROBLEM TO BE SOLVED: To selectively distinguish sulfur (sulfide sulfur) present as a sulfide in sulfides such as copper sulfide ore and copper concentrate from sulfur (sulfate sulfur) oxidized and present as a sulfate. Provide a method for quantitative analysis. SOLUTION: To a sulfide such as copper concentrate placed in a reaction vessel 1, a base metal rather than a metal forming the sulfide, a metal salt such as stannous chloride, and an acid solution are added, Stir the resulting slurry. Hydrogen generated from the reaction of metal and acid generates hydrogen sulfide from sulfide sulfur in the sulfide, and the generated hydrogen sulfide gas is led to absorption containers 4 and 4 and absorbed in the absorption liquid, and ICP emission spectroscopic analysis Measure with [Selection] Figure 1 |
