| titleOfInvention | The method that the sulfide that arsenic is prepared in waste material is produced from gallium arsenide chips |
| abstract | The invention discloses a kind of method that the sulfide that arsenic is prepared in waste material is produced from gallium arsenide chips, by gallium arsenide chips production waste material by broken, grinding, chip powder is well mixed with sublimed sulfur, heated, evaporated under nitrogen atmosphere, being condensed, sulphur removal, the sulfide of hypotoxicity arsenic is prepared.The present invention is not only effectively extracted the arsenic in gallium arsenide chips production waste material, and in extraction process, gallium is also stably remained in crucible with sulphided form, is enriched with.Present invention advantage in terms of reducing environmental pollution and improving resource utilization protrudes, and has the characteristics that cost is low, efficient, pollution-free. |
