The determination of gold and silver in plant liquors and electrolytes by atomic-absorption spectrophotometry
Abstract
An atomic-absorption method for determining gold and silver in solutions of varying complexity and variable composition in one set of standard solutions is suggested. The sensitivity of the method is 0·05 µg ml–1 and the coefficient of variation is 2 to 3 per cent.
The interference of cations and anions on the absorption analytical lines of gold 242·8 nm and silver 328·1 nm has also been investigated.
