Volumetric Determination of Lead

Volumetric determination of columbium.

The quantitative determination of columbium based on reduction by amalgamated zin c and reox idation with potassium permanganate has, in general, produced results that lack both accuracy and precision. A study of t he various factors involved indicates that essential conditions requ ire adequate duration of reduction in t he presence of an excess of zinc and a proper concentration of both acid ...

Cl. the Determination of Lead

FURTHER experience of the method of Tompsett & Anderson [1935] for the estimation of lead in human tissues and excreta has shown that in the analysis of different types of material modifications are an advantage in special cases. Also certain general improvements make it desirable to describe the method in more detail. A survey of the various methods for estimating minute amounts of lead in bio...
