Abstract

Abstract: In this paper,the concentration of amino group onto aminopropylsilanized(APS)quartz was measured by using contact angle method.Using phenol as a probe, the weak acid (phenol in CH₂I₂ solution)/the base(APSquartz) adsorption was studied in detail, and the surface concentration of amino group on APSsurface was calculaled as 1.14 nm²/mole when the Langmuir isotherm was used.And further ,SAzoNC₆OH acted as a probe, the surface adsorption concentration and molecular section area was indetified by using UV-visible absorption spectra.Comparing the area of per amino group of 0.41 nm2 from adsorption spectra measurement, a densed packing model, with hydrogen bonding existing between amino groups, was proposed.

Key words: Monomolecular layer, Contact angle, Langmuir isotherm adsorption
