- Abstract
Adsorption of (1-pentyl-1H-indol-3-il)(4-ethylnaphtalene-1-il)methanone on blended black and white hair samples was studied. Absolute adsorption amount was calculated for both hair types. Also adsorption isotherms were constructed and analyzed using different adsorption models. It was estimated that adsorption of (1-pentyl-1H-indol-3-il)(4-ethylnaphtalene-1-il)methanone is best described by Freindlich model which characterizes hair surface heterogeneity. Total amount of electron acceptor centers of hair surface was estimated using pyridine adsorption. Depending absolute adsorption of (1-pentyl-1H-indol-3-il)(4-ethylnaphtalene-1-il)methanone on surface acidity was found. It was suggested that analyte’s adsorption on hair depends on melanin amount. This idea explains that absolute adsorption on black hair is higher than on white
