在有色矿山铅锌的生产过程中,无论原矿、中间产品、精矿或尾矿,对铅锌的分析几乎都同时要求。由于铅锌极谱性能良好,因此原矿、尾矿等低含量铅锌样品的分析几乎都采用极谱法。我们采用氯化钙底液用改变极大抑制剂的方法,实现了在氯化钙底液中铅锌的同时测定,提高了分析速度,保证了分析的准确性。极大抑制剂的选择众所周知,动物胶是被广泛采用的经典极谱极大抑制剂。但动物胶易腐烂变质,不但腐烂的动物胶有许多不良影响,即使新配的动物胶也有许多不良影响,使本来有很好波形的离子,由于加入
In the production of lead and zinc in non-ferrous mines, almost all of the analysis of lead and zinc is required at the same time, regardless of raw ore, intermediate products, concentrate or tailings. Due to the excellent performance of lead-zinc polarography, polarographic analysis is almost always used in the analysis of low-level lead and zinc samples such as ore and tailings. We use calcium chloride at the end of the solution to change the great inhibitor method to achieve the simultaneous determination of lead and zinc in the calcium chloride bottom solution to improve the analysis speed to ensure the accuracy of the analysis. The choice of a great inhibitor As we all know, animal glue is a widely used classical polarographic maximal inhibitor. However, perishable animal gum perishable, not only rotten animal glue has many adverse effects, even with the new animal glue also has many adverse effects, so that there will be a good waveform of ions due to adding
