title: Determination of manganese in environmental samples (e.g. coal fly ash) by electrothermal AAS after its separation with a liquid chelating ion exchanger.
abstract: An electrothermal atomic absorption spectrometric method is described for the determination of manganese in various coal fly ash samples after its separation with dissolved monothioxo-beta-diketone as chelating ion exchanger. The detection limit is 1 ng ml(-1). To study the accuracy of the method, a reference material of similar composition was analysed and recovery of spiked manganese was performed.
