Simultaneous deternubation of the contents of phenol and resorcinol in compound resorcinol paint by linear combination method of absorbances

摘要

Linear combination method of absorbances was used for the simultaneous determinationof phenol and resorcinol whose absorption spectra overlap severely in the compound resorcinolpaint.The determination wavelengths were 265.0nm,270.0nm,273.4nm and 278.0nm.The averagerecoveries for phenol and resorcinol were 100.28±0.30% and 99.52±0.22%,respectively.
