| 选用480 nm单色光及长光程技术进行吸光光度分析，测定水质色度。通过对比普通分光光度法可知，吸光光度测试的光程长度增加10倍，测试灵敏度显著提高，从而保证低色度饮用水（<30度）的测定精准度。监测的色度数据利用GSM无线通信传输系统，可实现对水质色度监测结果的远程实时动态遥传，为预警突发性水污染事故提供数据支撑。 |

| Abstract: |
| In this paper,long optical path length spectrophotometry was used to determine the colority of water,which chose 480nm as the wavelength of monochromatic light. 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. |
