Fig. 3.8 Calibration graph for the determination of concentration of Phosphorus
After 10 min, but before 12 min, the color of the mixed sample was photometrically
measured at 690 nm in spectrophotometer and the absorbance reading was compared
with a calibration curve to get the value of phosphorus concentration. The calibration
curve used for the determination of total phosphorus is shown in Fig. 3.8.
