摘要：

A new digestion technique is presented for simultaneous analysis of particulate organic nitrogen (PON) and particulate organic phosphorus (POP) collected on filters. This method is based on a standard persulfate digestion procedure at 120-degrees-C and adapted from a former method for the simultaneous determination of total nitrogen and total phosphorus in natural waters. Comparisons with usual methods using separate determinations for PON and POP indicate a high efficiency of the procedure for cell cultures or natural seawater samples. Nitrate and phosphate formed by oxidation can be analysed simultaneously on an automated system. The procedure is highly suitable for routine analysis and especially appropriate for shipboard use.
