Identifikasi Cepat Minyak Atsiri Berdasarkan Pengamatan Spektrum Fluoresensi

Abstract

Have been rapid identification to some oil atsiri that is Olive Oil , VCO ( virgin coconut oil ), minyak sereh and minyak nilam by method analyse spectrum fluorescence. Spectral properties of fluorescence that is wavelength of absorption, wavelength of emission is 365 nm, 360 nm, 360 nm and 509 nm , respectively. Whereas Stokes Shift and quantum efficiency is 87 nm and 0,75, 42 nm and 0,88, 115 and 0,91, 33 nm and 0,71 , respectively ,have been calculated. Besides identifying to pure oil , also identify to oil which have been given by mixture kerosin. The spectral properties of fluorescence is be different . Analyse spectrum from given by oil of this mixture indicate that relation of mixture rate to intensity fluoresensi is linear. At this research have also been compiled by a database about fluorescence data from various substance what taken away from various literature.
