| Abstract |
A spectrophotometric method is proposed for determining sodium sulfide in workplace air in cupro-molybdenum ore flotation, where silver is used as a flotation reagent. The ability of sodium sulfide to react with silver salts and form a coloured product is used. The lower limit of sodium sulfide determination is 5µg, and the upper 40µg. Ions of metals which form sulfides interfere with the determination. |
