Paper Abstract

With the rapid development of the society and living standard, the water resources have been polluted more and more seriously, which is threatening the health of people and producing of the industry and agriculture. To protect the sustainable water resource, the monitoring of the water quality became an urgent task. There are some methods used to monitor the water quality, including the liquid chromatograph(LC), electrolysis method, electrochemical method, colorimetry method, atomic absorption spectrometric method, etc. But some drawbacks are existed in these methods. So, a fluorescence spectrophotometry method is adopted into this paper. And a novel water quality monitor(WQM) is designed. Meanwhile, in order to improve the spectral resolution and prevision, an improved spectrophotometer(SPM) based on holography concave (HC)grating is designed. In addition, the linear CCD with combined data acquisition (DAQ) card is used as the spectral detection system and virtual instrument(VI) technology based on LabVIEW is used to control the spectral acquisition and analysis. Experimental results show that the performances of the novel SPM for WQM are improved, its resolution can reach 2nm, the stray-light is less and the checking prevision of this WQM is higher than others. Therefore, the novel SPM for WQM has the potential value in the water quality monitoring and biochemical application.
