ABSTRACT
OBJECTIVE:
To establish a simultaneously detecting method for 9 kinds of anion in workplace air by ion chromatography.METHODS:
Nine kinds of anions in workplace air include fluoride ion,chloride ion,nitrite ion,bromide ion,nitrate ion,sulfate ion,phosphate ion,oxalate denominationbl and iodide ion were sampled with sodium carbonatesodium bicarbonate( concentration 3. 2,1. 1 mmol/L respectively),separated by the anion column,detected by the conductivity detector and quantified by external standard method.RESULTS:
The linearity of the 9 anions in the corresponding mass concentration range was good( correlation coefficient > 0. 999). The detection limit was 0. 02-0. 18mg/L and the marking recovery was 96. 0%-100. 5%. The within-run relative standard deviation( RSD) was 0. 3%-2. 5%,and the between-run RSD was 0. 4%-3. 1%. All the sampling efficiencies were > 96. 8%,and the samples could be stored at room temperature for 5 days.CONCLUSION:
The method has good accuracy,high sensitivity,with simple and rapid operation,and can simultaneously measure various anions in the air of workplace.
