在含有8—羟基喹啉和硝酸钠的介质中,钼产生一个极谱催化波,其峰电位Ep=-0.40V(vs.SCE),在50ml体积中Mo(Ⅵ)量在0.01～1.20μg范围内,峰电流与浓度成正比。用丙二酸掩蔽铁,不用分离可以直接测定钢中的钼。
In a medium containing 8-hydroxyquinoline and sodium nitrate, molybdenum produces a polarographic catalytic wave with a peak potential Ep = -0.40 V (vs.SCE) and an amount of Mo (VI) in a volume of 50 ml between 0.01 and 1.20 μg Within the range, the peak current is proportional to the concentration. Masked iron with malonic acid, without separation can be directly measured in molybdenum steel.
