Abstract
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.
