摘要
A previous finding that C. I. Disperse Yellow 67 does not conform to the Beer-Lambert law is shown to be caused by the presence of impurities in the presscake. Purified dye has been shown to obey the Beer-Lambert law. Nonconformity to Beer-Lambert, manifested by negative regression intercepts in absorbance/concentration plots, appears to be associated only with interactive fluorescence.
