摘要
本文利用紫外分光光度计,在pH=4.0的HAc-NaAc缓冲介质范围内,波长750nm下,测定植酸中游离磷的含量,实验结果表明在0—2.0ug/ml吸光度与浓度呈现良好的线性关系(r=0.9999),回收率在98.22—100.31％之间。
In UV method is used in the determination of free phosphorus in Phytic acid under the condition of PH=4. 0 and wavelength of 750nm. The results indicates good linear relationship between Absorbance and Concentration within 0-2. 0μg/ml (r= 0.9999). The recovery is 98.22-100.31 % .
