Selective determination of acenaphthylene by flow injection analysis with tris(2,2'-bipyridine)ruthenium(II) chemiluminescence detection.
A simple, rapid flow injection chemiluminescence (FI-CL) method has been developed for selective determination of acenaphthylene (ACY), based on the CL produced in the reaction of tris(2,2'-bipyridine)ruthenium(III) (Ru(bipy)3(3+)) and ACY in an acidic buffer solution. Under the optimum experimental conditions, the calibration curve was linear over the range 5.0 x 10(-3) to 4.0 x 10(-7) mol L(-1) for ACY. The detection limit (S/N=3) was 2.0 x 10(-7)mol L(-1) and the relative standard deviation of 10 replicate measurements was 2.3% for 5.0 x 10(-5)mol L(-1) of ACY. Selectivity of CL reaction of ACY from other 15 polycyclic aromatic hydrocarbons (PAHs) was investigated by flow injection method. The method was applied to determine the ACY content in soil.
