説明
Tap water always contains more than 0.1ppm chlorine for disinfection. The residual chlorine was determined with 2, 7-fluorenediamine(FDA) spectro-photometrically. Ten ml of the sample water, which contained less than 1.5ppm chlorine, was transferred to a 15ml test tube with a ground stopper. One ml of 2M nitric acid and 1ml of 40mg/l FDA solution were added and shaken. After 3min the absorbance was measured at 422nm. The calibration curve showed a straight line which passed through the origin and the molar extinction coefficient was 5.1×104l mol-1 cm-1. Coexisting cations and anions in tap water did not interfere with the determination.
