摘要：

An ultramicro technique for the digestion of organic N and P compounds in wastewater samples is described. The digests are analyzed simultaneously for phosphate and ammonia in the range of 0.02-2.00 mg P/l and of 0.06-10.00 mg N/l using automated spectrophotometry at the rate of 30 samples/h. The accuracy, precision and tolerance to common interferences of the ultramicro method are discussed. Comparability testing of the ultramicro and standard methods shows a small but statistically significant difference for the P but not for the N results.
