As. Carretero et al., OPTIMIZATION AND COMPARATIVE-STUDY OF THE ROOM-TEMPERATURE PHOSPHORESCENCE OF ACENAPHTHENE IN BETA-CYCLODEXTRIN IN THE PRESENCE OF 2 BROMOALCOHOLS, Applied spectroscopy, 52(3), 1998, pp. 420-425
A multivariate optimization approach, using a central composite blocke
d cube-star design, has been carried out to optimize the room-temperat
ure phosphorescence (RTP) of a ternary complex between a polycyclic ar
omatic hydrocarbon (acenaphthene), beta-cyclodextrin. and two bromoalc
ohols (2-bromoethanol and 2,3-dibromopropanol). A comparative study of
the effect of the two bromoalcohols in the phosphorescence response h
as shown that the highest RTP emission from acenaphthene included in b
eta-CD is obtained with 2,3-dibromopropanol. An RTP determination meth
od for acenaphthene has been proposed. Calibration graphs range betwee
n 50 and 250 ng mL(-1), and a detection limit of 24 ng mL(-1) has been
established.
