饮用水中亚硝酸盐的测定与分析

亚硝酸盐与人们的生产生活及个体健康息息相关。本文测定了市售的5种品牌的饮用水中开启不同时间的亚硝酸盐含量并研究了煮沸后放置不同时间、煮沸次数对自来水中亚硝酸盐含量的影响。结果表明,5种品牌的饮用水在刚开启时和开启当天均未检出亚硝酸盐,隔夜和1周后亚硝酸盐含量增高;自来水煮沸后放置时间越长,亚硝酸盐含量越高,煮沸次数越多,亚硝酸盐喊来那个越高。

Determination and Analysis of Nitrite in Drinking Water

Nitrite production and people’s life and health are closely related individuals. This article was measured ifve commercially available brands of drinking water in the open at different times of the nitrite content and the effect of placing at different times after boiling, boil tap water times the nitrite content. The results showed that ifve brands of drinking water in the open and on the same day just was not detected in nitrite, and nitrite levels increased overnight after a week; after the longer storage time boiling water, the higher the nitrite content, boil the more times, shouted to the higher nitrite.
