无干扰法检查纯水中重金属

Detection of Heavy Metals in Purified Water by Non - interference Method

目的:科学地控制纯化水中重金属的限度。方法:采用精制处理后的检查专用试验水,按《中国药典》方法检查纯化水中的 重金属。结果:精制处理后的检查专用试验水用于检查纯化水中的重金属可排除干扰。结论:精制处理后的检查专用试验水中的重 金属含量限定在极微量范围内,可极大地减少干扰,使检查结果更加准确。

OBJECTIVE;To scientifically control the limit of heavy metals in purified water.METHODS：Heavy metals in the purified water were detected by the refined testing water specifically for detection in accordance with Chinese Pharmacopoeia .RESUI.TS： Interference could be removed by using the refined testing water in the detection of heavy metals in the purified water.CONCLUSIONS： Limiting the contents of heavy metals of refined testing water to a minimum range can reduce interference to a large degree, thus making the detection results more accurate.
