摘　　要：用乙酰丙酮作显色剂 ,在 412nm处 ,用分光光度法可测定微量甲醛。对甲醛标准溶液的标定、显色剂选取、显示时间、干扰因素进行了探讨 ,确定较为合理的测定条件 ,获得比较准确的测定结果。By using acetyl acetone as color reagents, the micro-formaldehyde can be determined at the point of 412nm with spectrophotometry. A research into the calibration of standard formaldehyde solution, the selection of color reagents, the developing time, and the disturbance factors is conducted in this paper. Thus the more rational determining terms and the more accurate determining result are obtained.
