Method for removing and for a qualitative - analytical determination of cyanide accomplished in contaminated

摘要

the procedure for removal and qualitative analytical determination of cyanide in cyanide contaminated soils is that so long gasstromes blow one of carbon dioxide, nitrogen, water vapour, oxygen or compressed air, biodegradable, organic acids in ground launched and the released hydrogen cyanide followed by oxidized.in the exiting gas quality of hydrogen cyanide and ammonia are no longer detectable. the method preferably takes place by injection of carbon dioxide and compressed air.
