摘　　要：通过对用异烟酸－吡唑啉酮法测定用碱性氯化法处理的电镀含氰废水中残留氰化物时所遇到的干扰问题的探讨，提出了用抗坏血酸代替亚硫酸钠作为消除余氯的还原剂．When using the alkaline chlorination to treat the electroplating waste water and then using the isonicotinic acid-pyrozolyl ketone method to determine the remainder cyanide in the waste water, the excess chlorine often interfered. In this work, the interference problems were studied and replaced the sodium sulfite with vitamin C as reducing agent to remove the excess chlorine.
