| titleOfInvention | Method for removing mercury in liquid |
| abstract | PURPOSE: To selectively remove mercury contained in a liquid, by adding arsenic sulfide to the liquid containing mercury. n CONSTITUTION: For example, mercury, rhenium, etc. are present in the waste acid in a sulfuric acid process generated in a non-ferrous refinery and arsenic sulfide prepared in the same non-ferrous refinery is added to the waste acid solution. By this method, mercury is recovered in the form of sulfide and, because arsenic is dissolved in the solution, the Hg-concn. of the recovered mercury sludge is high. Because rhenium does not react with arsenic sulfide, Hg can be selectivity converted to sulfide and, thereafter, rhenium can be easily recovered and, further,the lowering of mercury in product sulfuric acid is also enabled. n COPYRIGHT: (C)1987,JPO&Japio |
