浮选技术渗透于分析化学仅有十余年历史,已成功地用于污水处理,水体中微量元素的富集,高纯金属中痕量元素的富集分离,络合物平均配位数的测定等,并作为光谱、原子吸收等的前处理。利用金属络离子和染料形成复杂结构的离子缔合物的浮选性能,可以把浮选和光度分析结合起来,这就是近年来发展起来的高灵敏和高选择性的浮选-吸光光度法(Flotation-spectrophotometry)。其特点是处理样品量大(如0.5~2升样品),分离系数大,回收率高(90%以上),摩尔吸光系数一般可达10~5级,容易自动化连
Flotation technology infiltration of analytical chemistry only 10 years of history, has been successfully used for sewage treatment, enrichment of trace elements in water, enrichment and separation of trace elements in high purity metals, complex average coordination number Determination and so on, and as a spectroscopy, atomic absorption and other pre-treatment. The flotation performance of complex ion-association complexes using metal ions and dyes to form complex structures allows the combination of flotation and photometric analysis. This is the highly sensitive and highly selective flotation-absorptiometry developed in recent years Flotation-spectrophotometry). It is characterized by large sample size (eg 0.5 ~ 2 liter sample), large separation coefficient, high recovery rate (over 90%), molar extinction coefficient generally up to 10 ~ 5, easy to automate with
