摘要
用紫外-可见分光光度法测定低浓度谷氨酸溶液:以λ=207nm为测定波长,谷氨酸浓度在0.02—0.12g/L范围内有很好的线性;以λ=401nm和λ=568nm为测定波长,茚三酮衍生后的谷氨酸溶液在0.02—0.07g/L范围内有很好的线性。此方法快速简便,结果准确,适合不同成分的产品分析与样品含量检测。
The lower concentration of glutamic acid was determined by UV/Visible spectrophotometry. With the detection wavelength the glutamic acid has a good linear relation during the range of 0. 02--0. 12g/L at 207nm. With the detection glutamic acid was derivated with ninhydrin,and determined in the range of 0. 02--0. 07g/L at 401nm and 568nm. This method is simply and quick and precise.
