Abstract: In this paper, we demonstrate the detection of organic compounds in water by applying an ultraviolet LED (280 nm) spectroscopy system and photodetector. The LED spectroscopy system showed a high correlation between the prepared potassium hydrogen phthalate (KHP) concentration and that calculated by multiple linear regressions, indicating an adjusted coefficient of determination from 0.953 to 0.993. In addition, a comparison between the spectroscopy system and total organic carbon analyzer indicated that the concentration differences were small. Based on the close correlation between the spectroscopy and photodetector absorbance values, organic measurement with photodetector could be configured for monitoring.
