Determination of the Arsenic in Iron Ore by ICP-OES Method
SHI Qiuying
Abstract：The simple was dissolved by adding hydrochloric acid, hydrofluoric acid and perchloric acid. Residual mixed acid in the solution was driven away by evaporation. Through optimizing experiments, the analysis method of testing the arsenic in iron ore by ICP-OES method was established. The best parameters of the instrument selected by experiment are as follows:plasma power 1 400 W, atomizing air flow 1.0 L/min, auxiliary flow 0.8 L/min and washing time 45 s, at the same time, the interference from matrix was eliminated by matrix matching and selected spectral lines are As189.042 nm and As 193.759 nm. The results showed that detection limit is less than 0.02μg/mL and the RSD<4%.
