补充资料：pH指示剂吸光度比值测定法
分子式：
CAS号：
性质：采用容量法与分光光度法相结合的一种差示定量法。其原理为选择一种适当的酸碱指示剂，其酸式色和碱式色的吸收光谱和吸收度有显著的差别，且该指示剂的pKa值在某一酸碱反应的化学计量点的pH值附近，当酸碱滴定时，在酸式色和碱式色的最大吸收波长λ1和λ2处分别测得其吸收度Aλ1及Aλ2，计算吸收度比值r′(r= )，便可通过滴定中r的变化而准确测 定样品含量。该法除用于弱碱性药物的测定外，还可用于磺胺类、氨基酸等的测定。JP(9)已收载用于水杨酸钠、枸橼酸钠、氨基比林、无味奎宁、烟酰胺等药物的测定，《中国药典》(1985)也已收载用于枸橼酸钠的测定。
