【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（APS quartz） adsorption was studied in detail, and the surface concentration of amino group on APS surface 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.更多还原
