芜湖市某化工厂周围水中挥发酚含量的调查

VOLATILE PHENOL IN THE ENVIRONMENTAL WATER OF A CHEMICAL PLANT IN WUHU

通过对芜湖市某化工厂周围环境水包括排放出口处的长江水中挥发酚含量测定，结果总均值Ｘ＝０．００２３０４ｍｇ·Ｌ－１。比国家规定生活饮用水标准０．００２ｍｇ·Ｌ－１略高，但不超过国家规定的地面水中挥发酚含量标准０．０１ｍｇ·Ｌ－１。所以该厂对周围水及长江水没有造成明显的酚污染，同时表明：不同时间和地点采样的水中挥发酚含量有差别。

By way of 4-aminoantipyrine colorimetry we have investigated the volatile phenol in the water near a chemicai plant in Wuhu , inluding the water at the drainge exit in the Yangzi River.The total average volatile phenol content in the water was X=0.002304mg·L-1. It was slightly higher than that of the national standard of drinking water(0.002mg·L-1),but much lower than that of the national standard of ground water(0.01mg·L-1). Therefore this chemical plant did not result in serious phenol pollution in its surrounding water.
