摘要
目的:探究不同冲洗方式对反渗透净水器浸泡试验耗氧量增加量的影响。方法:采用红外光谱法、气相色谱-质谱联用法对反渗透净水器浸泡水进行成分分析。结果:结果表明,某市售反渗透净水器浸泡水含有0.2%的甘油成分;在不冲洗、冲洗半小时、间歇冲洗24 h的冲洗条件下,浸泡试验耗氧量增加量分别为159 mg/L、3.5 mg/L、0.2 mg/L。结论:本研究表明,反渗透净水器初次使用耗氧量超标可能由甘油引发,因甘油引发的耗氧量异常能够通过加长冲洗时间避免可能产生的健康影响。
Objective: Explore the influence of different flushing methods on the increase in oxygen consumption in the immersion test. Methods: Use infrared spectroscopy and gas chromatography-mass spectrometry to analyze the immersion water of the reverse osmosis water purifier for component analysis. Results: The results show that the water after soaking in a reverse osmosis drinking water treatment units contains 0.2 % glycerin. The increase in oxygen consumption of the immersion test is 159 mg/L, 3.5 mg/L, 0.2 mg/L under the flushing mode of the water purifier without flushing, flushing for half an hour, and intermittent flushing for24 hours. Conclusion: This study shows that the excess oxygen consumption of the reverse osmosis water purifier used for the first time may be caused by glycerin,Abnormal oxygen consumption caused by glycerin can avoid possible health effects by lengthening the flushing time.
