【摘要】 在氢氧化钾-溴邻苯三酚红的溶液中,镁有一灵敏的极谱波,峰电位为-1.32V(vs.SCE),镁浓度在0.01—0.6μg/mL范围内与波高成线性关系,成功地应用于指甲中微量镁的测定,並采用极谱连续变化法测得络合物组成比为1∶1。更多还原

【Abstract】 The polarographic adsorptive wave of magnesium in 0.010M potassium hydroxide and bromopyrogallol red (BPR) solution has been studied. Ep equals to-1.32V (vs.S.C.E.). The peak height is linearly proportional to the magnesium content in nail . The composition ratio of Mg-BPR complex has been studied by continuous variation method to be 1: 1.更多还原
