IR-SPECTROSCOPIC METHOD OF DETERMINING SIZES OF PORES OF MICRO-POROUS MATERIAL |
摘要 |
FIELD: measuring technique. ^ SUBSTANCE: method comprises producing reference specimens with a standard diameter of the pores and having the same chemical nature as the specimen to be analyzed, recording IR-spectra of transmission of the reference specimens, determining the value of the wavenumber for which the IR-radiation transmission is 50% (point of inflection), and obtaining reference histograms. The sizes of pores are judged by the position of the points of inflection in the transmission spectra. ^ EFFECT: enhanced precision. ^ 6 dwg |
