A METHOD AND SYSTEM FOR QUANTIFYING A CONCENTRATION OF ANIONIC SURFACTANTS IN A SAMPLE

摘要

A system and method of quantifying a concentration of anionic surfactants in a sample, the method including: contacting a cationic dye with the sample and a solvent, such that an anionic surfactant in the sample complexes with the cationic dye to form a detectable dye-surfactant complex that is preferentially soluble in the solvent; obtaining image data of the dye-surfactant complex in the solvent; for a plurality of pixels in the image data, generating RGB colour space values by applying one or more filters to the image data; analysing the RGB colour space values to derive a concentration of the anionic surfactant in the sample; and outputting an indication of the concentration of the anionic surfactant in the sample.
