摘要
研究了赤霉素作新还原剂还原锗钼酸铵的显色反应，在０．５０２５ｍｏｌ／ＬＨ２ＳＯ４介质中，赤霉素能将锗钼酸铵还原成锗钼蓝，其最大吸收波长为８０５ｎｍ，摩尔吸光系数为２．４２×１０４Ｌ／ｍｏｌｃｍ，线性范围为０～３０μｇ／２５ｍＬ，显色液色泽十分稳定，可用于锗的分光光度测定。
The color reaction of Ge Mo heteropoly acid with gibberellin as new reducing agent is studied. In the media of 0.5025 mol/L H 2SO 4,the Ge Mo heteropoly acid is reduced to Ge Mo heteropoly blue by gibberellin, which exhibits maximum absorption at 805 nm with molar sbsorptivity of 2.24×10 4 L/ mol·cm and linear range of 0～30μg/25mL.
