天然水中酚的含量极少 ,但由于存在着工业废水污染问题 ,使饮用水很可能含有酚类化合物。另外由于食品罐头内壁使用环氧酚醛等涂料 ,也可能使罐头内食品受到酚类化合物的污染。这些都威胁着人们的健康。因而 ,我们必须对饮用水和食品包装材料中的酚含量进行监控。现在测定酚的
Phenolic content in natural water is minimal, but because of the problem of industrial wastewater pollution, drinking water is likely to contain phenolic compounds. In addition, the use of epoxy phenolic and other coatings on the inner wall of food can also contaminate the food in the cans with phenolic compounds. These are threatening people’s health. Therefore, we must monitor the phenolic content of drinking water and food packaging materials. Now determine the phenolic
