This document specifies a steam distillation and ion chromatography method for the determination of the mass fraction of total fluorine and chlorine in iron ore as follows.
a) This method is applicable to the determination of mass fractions of fluorine from 0,005 % to 0,50 %.
b) This method is applicable to the determination of mass fractions of chlorine from 0,008 % to 0,50 %.
Ion chromatography (IC) appeared as a simple and efficient analytical technique that has been widely used for the routine analysis of ions especially halogens, nitrates, sulphate etc. IC offer green method for the analysis of inorganic ions, cause it need only water and small amount of alkali solution as an eluent. Moreover, it offer multiple advantages such as its low cost, selectivity, sensitivity, and most importantly its accessibility to most of the developing countries laboratories as compared to other expensive and heavy analytical techniques.
Therefore, this standard describes an option for the sensitive and cost-effective method for the simultaneous determination of fluorine and chlorine contents in complex iron ore samples.
This standard is cost-effective, green and simple to conduct.
