| Abstract |
The main finding of this research was the fluorescence and light scattering properties of water, their relationship with corresponding NOx(NO_2+NO_3). Chlorophyll-a values and the correction for interference matter. The samples obtained from surface and domestic water. In experimental conditions, spectrum of NOx(NO_2+NO_3) detected at excitation/emission wavelength 220/220nm and Chlorophyll-a detected at 430/677nm. All spectrum were performed using in scan mode, scan speed 300nm/min, excited/detected spectrum band width 5nm, and xenon lamp(20kW) as light source. The correlation between NOx(NO_2+NO_3) and light scattering intensity values, and the Chlorophyll-a were high. Especially the NOx(NO_2+NO_3), the calculated values by multiple regression using predictor variables highly correlated to the observed values. The result investigates the possibility of using a scattering technique for application of rapidly real-time and on-line monitoring of NOx(NO_2+NO_3) and Chlorophyll-a values. |
