Rapid determination of eight elements in cement and its raw mixes by inductively coupled plasma atomic emission spectrometry

Abstract

An investigation was carried out on the influence of the operating conditions and of the analytical performance characteristics of inductively coupled plasma atomic emission spectrometry for the determination of eight elements (Si, Al, Fe, Ti, Ca, Mg, Na and K) in the raw components of cement. The aim of this investigation was to develop a rapid method of quality control for such raw materials. The results showed that this technique is sensitive enough for each element of interest and no serious interferences were detected after a detailed inter-element interference study. Rapid determination by automatic sequential analysis of the eight elements in a single solution of the sample proved to be highly satisfactory. A suitable fusion method for non-clinkerised material, normally difficult to dissolve, is also given.
