| 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 CH_2I_2 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. |
