| 摘 要： | 对采用次灵敏线测定地表水中高含量的钾、钠、钙、镁的灵敏度、检测限、线性范围、共存元素的干扰情况以及精密度和准确度进行了研究,发现该方法线性范围宽,精密度好,准确度高,与标准法(灵敏线)相比,相对误差<3%,满足分析需要。同时标准曲线系列常温下放置至少可稳定1a,避免了每次测定水样都要制作标准曲线的麻烦,既节省了试剂,又减轻了工作量,具有较高的实用价值。

| Abstract: | Sensitive line was used to detect sensitivity, detection limit, linear range, disturbance and accuracy of high content of potassium, sodium, calcium and magnesium in surface water. Results showed that the method is wide in linear range and good in accuracy with relative error less than 3% comparing with conventional method. |
