The determination of silicon by atomic-absorption spectrophotometry, with particular reference to steel, cast iron, aluminium alloys and cement

Abstract

The determination of silicon by atomic-absorption spectrophotometry in silicon-containing and siliceous materials has been investigated. Means are outlined by which many types of sample can be completely dissolved without loss of silicon, thus avoiding the need for fusion. Full operating details are given, and the results, accuracy and sensitivity of the method are discussed.
