原子荧光法测定水中硒时，铜元素的存在会对硒的测定造成干扰。该文通过大量试验优化条件参数，增加盐酸浓度或加入氯化铁溶液，总结出测定水中硒去除铜干扰的最佳条件，并对该条件下的精密度和准确度进行了评估。结果表明盐酸浓度20％或加入0．6 mL 10 g ／ L的氯化铁能有效抑制铜元素对硒的干扰，且操作简便、数据准确可靠。
原子熒光法測定水中硒時，銅元素的存在會對硒的測定造成榦擾。該文通過大量試驗優化條件參數，增加鹽痠濃度或加入氯化鐵溶液，總結齣測定水中硒去除銅榦擾的最佳條件，併對該條件下的精密度和準確度進行瞭評估。結果錶明鹽痠濃度20％或加入0．6 mL 10 g ／ L的氯化鐵能有效抑製銅元素對硒的榦擾，且操作簡便、數據準確可靠。

The determination of selenium in water through atomic fluorescence spectrometry method will be interfered by copper. A lot of experiment for increasing concentration of hydrochloric acid or dosing ferric chloride was made in order to find the best determination condition of selenium while interference-free from copper,and the accuracy and precision of datum were analyzed. The results show that the optimum conditions are as follows:concentration of hydrochloric acid is 20% or 0. 6 mL 10 g / L ferric chloride is added. The method is simple and accurate for the determination of selenium in water.
