摘要
利用DX - 12 0离子色谱仪进行阴阳离子的精密度和准确度测定 ,10 0mg/L时相对标准偏差范围为 1 0 0 %～ 3 80 % ,回收率 95 83%～ 10 5 0 0 % ;5mg/L时相对标准偏差范围为 1 18%～4 5 7% ,回收率 92 4 0 %～ 10 3 2 0 % ,完全达到实际要求。用该离子色谱仪测定甘肃阳山金矿区水样中常规无机离子 ,数据表明该区域水质较好 。
The precision and accuracy of negative and positive ions can be determined by Model DX-120 Ion Chromatography Instrument, recovery is between 95 83% and 105 00% when concentration is 100 mg/L and RSD is between 1 00% and 3 80%. Recovery is between 92 40% and 103 20% while concentration is 5 mg/L and RSD is between 1 18% and 4 57%.So it is up to the standard of the reality. Also water samples collected from Yangshan gold deposit in Gansu Province, and the result showed that this district had good quality of water,the measused Ion concentration were all in the drinking water standard.
