摘　　要：通过对乙酰丙酮荧光分光光度法测定空气中甲醛的试验条件用单因素改变法与单纯形优化法试验结果进行对照 ,确定了测定空气中微量甲醛的最佳试验条件。该方法的最大激发波长为 4 15 nm,最大发射波长为 5 0 8nm,最低检测限为 0 .0 0 34μg/ml。对空白值测定的标准偏差为 0 .0 0 0 6μg/ml,相对偏差为 5 .6 %。测定空气中甲醛的最低浓度为0 .0 0 5 7mg/m3。By determining formaldehyde trial condition with acetyl acetone spectrophotometer,compared single factor change and result of simple optimise,then confirmed that the optimal trial condition of formaldehyde in the air.In this measure,the maximal excited wave length is 415nm,the supreme emission wavelength is 508nm,the lowest inspectness is 0.0034μg/ml.The standard deviation of blank value is 0.0006 μg/ml,relative deviation is 5.6%.The lowest detective concentration of formaldehyde in air is 0.0057mg/m 3.
