摘要
A method for assaying anionic detergents in seawater comprises: (1) flow a sample through a sample system and an analysis-detection system; flow a reference solution through a reference system, a valve, and the analysis-detection system; where the sample and reference are mixed; and flow the mixture into an optical cell to produce a baseline, (2) flow a sample through the sample system and analysis-detection system; flow a buffer through a buffer system and a color developing system; where the buffer and a color developer are mixed; and flow the resulting mixture through the valve and analysis-detection system; where the sample is mixed with the buffer and developer mixture; and flow the resulting mixture into the cell to produce the sample spectrogram, (3) repeat (1) and (2) with standards of known detergent concentrations for corresponding spectrograms, and (4) compare the sample spectrogram with the standard spectrograms to determine the sample detergent content.
