| Abstract: | Total phosphorus in water was determined by microwave digestion-spectrophotometry, using potassium persulphate as the reducing agent. The best experiment conditions were confirmed on the basis of investigation on many factors such as wavelength, the amount of the reducing agent, power and time. And the effect of ions was also investigated. The average recovery was 98.64 % and the ralative standard deviation were in the range of 0.5 %-2.5 % by the determination of watersamples. |
