摘　　要：研究了酒石酸硝酸锌法提取易释放氰化物 ,磷酸EDTA提取总氰的机理 ;对异烟酸吡唑啉酮光度法测定氰化物的条件作了探讨。The mechanism to extract easily-released cyanide with the method of dihydroxysuccinic acid-zinc nitrate and to extract total cyanogen by way of phosphoric acid-BDTA is studied. The conditions for determining cyanide with the isonicid-pyrazolinone photometric method are approached.
