摘要
介绍了催化极谱法测定化探样品中钨、钼前处理方法的选择及硫酸浓度对灵敏度的影响。在传统常用方法的基础上,用二苯胍代替辛可宁,用二苯羟乙酸代替苯羟乙酸,能够很好地消除干扰并提高灵敏度。
This paper introduces the catalytic polarographic method for the determination of geochemical samples of tungsten and molybdenum in the sample treatment method selection and concentration of sulfuric acid on the sensitivity of the influence. On basis of traditional methods and diphenyl guanidine instead of cinchonine and benzilic acid instead of mandelic acid,can be very good to eliminate the interference and improve the sensitivity.
