Compared with the conventional spectrophotometry,the sensitivity of this method was greatly improved with the optical path enhanced 10 times,which could be suitable for the determination of low chroma water (<30 degree). The monitoring data was transmitted by GSM wireless communication system. So the real time dynamic remote transmission of the water colority was realized,and the intelligent water system for early warning of unexpected water pollution accidents was established. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
