摘要: Abstract The strength and the nature of interaction hydroxylated dehydroxylated silica with chosen adsorbates was interpreted on basis heat adsorption simple organic molecules (probes) approximately same shape but significantly different dipole moments relative basicities. Flow microcalorimetry used for measurements (displacement). In all cases, highest heats silica, in range from − 10 to 30 μJ cm −2 , were found basic substances, regardless their moment. These results supported by immersion measurements, using batch calorimetry amino spin probe displacement, measured electron resonance (ESR).
