Abstract:
1. A method for automatic assay of anionic detergents in seawater using an analytical apparatus comprising a flow system for buffer solution, a flow system for color developer solution, a flow system for reference solution, a flow system for samples, a sample valve and a flow system for analysis and detection, wherein the method comprises the following steps: (1) allowing a testing sample (S) to flow along the flow system for samples and into the flow system for analysis and detection, and allowing a reference solution (R (2) allowing the testing sample (S) to flow along the flow system for samples and into the flow system for analysis and detection, and allowing a buffer solution (R (3) repeating steps (1) and (2) with a series of standard samples having known concentrations of an anionic detergent instead of the testing sample (S) to obtain a series of spectrograms of the standard samples; and (4) comparing the spectrogram of the testing sample (S) with the series of spectrograms of the standard samples to determine the content of the anionic detergents in the testing sample (S); wherein the testing sample (S) is seawater, the buffer solution (R
