摘要
NaOH滴定葛根黄豆甙元的电导实验表明:它足一个二元酸。用紫外分光光度法测定了它的电离常数,其pK_(1a)和pK_(2a)值分别为7.48±0.04和9.53±0.04.
Experiments of conductometric titration of Daidzein with NaOH revealed that Daidzein is a dibasic. Its ionization constants were determined by ultraviolet spectrophotometric method, the pK_(?) and pK_2. values being 7.48±0.04 and 9.53±0.04 respectively.
