Abstract

Spectrum based water quality analyzer for comprehensive organic pollution index evaluating is a kind of green measurements with prosperous futures. Due to the low estimation precision of single-spectrum based analyzer and the complementary advantages of multi-spectrums, a modeling method based on information fusion of the ultra-violet absorption spectrum and the fluorescence emission spectrum is adopted for rapid measure of organic pollution indices such as COD, TOC, etc. A module structure is designed for portable realization to perform the field mobile tasks and rapid scene measurements. The experimental results show that this instrument possesses a better prediction capability than single UV based instruments popular in the market.
