【摘要】 本文报道一种新的测定δ－氨基乙酰丙酸（δ－ＡＬＡ）的分光光度法．方法基于δ－ＡＬＡ被缩合成呲咯衍生物后，在酸性条件下与Ｆｅ３＋生成橙红色配合物，其λｍａｘ为４８０ｎｍ，ε为６．６×１０３Ｌ·ｍｏｌ－１·ｃｍ－１，线性范围１０～４００μｇ／２５ｍＬ，回收率９４～１０４％．更多还原

【Abstract】 The paper was reported a new spectrophotometry determination of δ aminolevulic acid (δ ALA) . It is based on that the pyrrole derivative condensed from δ ALA can react with Fe 3+ under acid condition and form vermilion complex. The maximum absorption is at 480nm with a molar absorptivity of 6.6×10 3L·mol -1 ·cm -1 . The linear range is over the range of 10￣400μg/25mL. The recovery is within 94￣104%.更多还原
