摘要
In the NaOH-NaCl-CH2（NH2）COOH medium,the reagent reacts with cethyltrimethylammonium bromide（CTMAB）and cteylpyrid-inium bromide（CPB）to form blue purple complex of component ratio 1∶2.The absorption maximum of the complex is at 565nm.The range of Beer’s law to be obeyed,apparent molar absorptivity and critical micelle concentration of the cationic surfactants were determined,respectively.
