Polarographic Determination Of Germanium, Calvin Leo Stevenson May 1953

Polarographic Determination Of Germanium, Calvin Leo Stevenson

Bachelors Theses and Reports, 1928 - 1970

In the past germanium has been determined by either wet methods or by the spectograph; the spectograph being used for the determination of very small amounts of ger­manium and wet methods used when more than one hundredth of one percent germanium is present. Both of these analyti­cal schemes have weaknesses.

The Effect Of Germanium On The Current Efficiency In The Electrolysis Of Pure Zinc Sulfate Solution, Keith R. Bock

Bachelors Theses and Reports, 1928 - 1970

It has long been recognized that electrolytic zinc cells are extremely sensitive to impurities. In fact, cer­tain impurities present in amounts as low as 0.1 mg/1 cause a serious loss of current efficiency. Also, the presence of several impurities in the electrolyte may accelerate the detrimental effect of each impurity.
