| Abstract: | The method for the determination of total phosphorous in the sewage sample was set up. The sewage sample was digested by microwave. The influence of digestion time, digestion pressure on analytical results was discussed. The linear range was 0~0.4 mg/L. The method was applied to the determination of the total phosphorous in environmental standard sample of total phosphorous, and the result was basically consistent with standard value, RSD was 1.64%. |
