A new and simple spectrophotometric method for the determination of selenium in the presence of copper and tellurium

Selenium in anodic slime is determined by using an indirect method. Selenite is reduced by ferrous iron, the ferric iron formed is complexed with KSCN, and the absorbance at 480 nm is measured. In this way selenium (10 −3 -10 −2  M) can be determined in the presence of copper and tellurium without a...

Zusammenfassung:Selenium in anodic slime is determined by using an indirect method. Selenite is reduced by ferrous iron, the ferric iron formed is complexed with KSCN, and the absorbance at 480 nm is measured. In this way selenium (10 −3 -10 −2  M) can be determined in the presence of copper and tellurium without any separation.
