Publisher Summary. Polarographic Determination of Aluminum in Rocks. book This chapter discusses the classical scheme for the analysis of silicate rocks. In the classical scheme of silicate rock analysis, separate portions has always been used for the determination of alkali metals, ferrous iron, moisture, total water, and usually for total iron, titanium, total manganese, and phosphorus.

Heyrovsk over 40 years ago application of polarographic technique is in analytical chemistry since it makes possible, in a simplified way, the detection and estimation of elements by this method'5.

Figure 3. Determination of lead in pure potassium nitrate by "sluice" increment method'5. A method is proposed for determination of zinc, indium, lead and copper in gallium.

The method is based on the ability of the metals to transfer from gallium into mercury. The gallium sample is placed on the stationary mercury-drop electrode. The voltammetric curve is recorded while the potential is scanned from − V to less negative by: 2.

The microanalysis of solutions of dioxouranium- (VI) has been investigated employing differential pulse polarography. These studies show that uranium and lead can be determined accurately and economically in the presence of each other. The lead current peak occurs at − V, the uranium peak at − V.

A polarographic method for the determination of micro quantities of uranium was developed. The method is based on the catalytic wave of uranyl ions which appear in the presence of nitrate ions. Several factors which affect the height and the potential of the wave were investigated.
