对用双乙醛草酰二腙分光光度法测定水中铜时的有关影响因素进行了分析实验，发现只要严格地控制操作过程中的溶液pH、显色温度和时间、冷却温度，并且在配置缓冲溶液时一定要调制pH值到9，在检测时就会收到准确度精密度都较好的测定结果．
대용쌍을철초선이종분광광도법측정수중동시적유관영향인소진행료분석실험，발현지요엄격지공제조작과정중적용액pH、현색온도화시간、냉각온도，병차재배치완충용액시일정요조제pH치도9，재검측시취회수도준학도정밀도도교호적측정결과．
This paper uses the double acetaldehyde two hydrazone spectrophotometric method for the determination of copper irt water by the related influencing factors are analyzed, and finds that as long as the strict control of operation in the process of solution pH, color tempera ture and time, cooling temperature, and pH to 9 must be modulated in the allocation of buffer solution, so as to get accuracy precision measure-ment result.
