摘要
主要研究了用ICS—2000型离子色谱仪测定水中不同硫酸根离子的浓度的标准偏差、精密度,及色谱图形。确定了测定水中硫酸根离子浓度在0.20~120 mg/L的范围内具有较好的准确度。
The standard deviation, precision and chromatogram of different concentrations of sulfate ions are studied. The concentrations are determined by ICS--2000 ion chromatograph. The sulfate ion＇s concentration range in 0.20-120 mg/L determined in water has better accuracy.
