説明
The precipitation of ternary complex of chrome-azurol S, Al3+ and quarternary ammonium ions was avoided by using polyethylene glycol-p-nonylphenyl ether n=10, and the stable solution was submitted to a spectrophotometric determination of quarternary ammonium ions. In the case of cetyltrimethylammonium bromide, the absorbance at 615 nm against reagent blank obeys Beer's law over the range between 5.0 and 50.0μg in a final volume of 15 ml, the ε value and coefficient of variation being 7.86×104 and 1.76%, respectively. This simple and highly sensitive method was applied to benzalkonium chloride and benzethonium chloride etc., although a few ions such as Fe3+ interfere the determination.
