A new fluorescent sensing microtiter plate (MTP) was developed for high sensitivity monitoring of anthracene in seawater samples. For this purpose, two ternary complexes of Tb(III) ions with dibenzoyl-methane and neocuproine [Tb(DBM)(2)(MePhen)] or with dibenzoylmethane and bathocuproine [Tb(DBM)(2)(PhMePhen)] were synthesized. Elemental analysis, energy dispersive X-ray analysis, X-ray diffraction, infrared and ultraviolet-visible emission, and thermal analysis were conducted on the Tb (III) complexes. The limits of detection (D-L) were 0.14 and 1.05 mu mol L-1 for [Tb(DBM)(2)(MePhen)] and [Tb(DBM)(2)(PhMePhen)], respectively. [Tb(DBM)(2)(PhMePhen)] MTP is embedded in a membrane made of cellulose acetate. The first high-throughput anthracene sensor MTP, based on [Tb(DBM)(2)(PhMePhen)] sensor showed a linear range, from 0.2 to 20 mu umol L-1. [Tb(DBM)(2)(PhMePhen)] MTP was validated for accurate and precise monitoring of anthracene using gas chromatography. The selectivity of the [Tb(DBM)(2)(PhMePhen)] MTP toward anthracene was examined. The data indicated that [Tb(DBM)(2)(PhMePhen)] MTP is suitable for rapid and direct detection of anthracene. (C) 2021 Elsevier B.V. All rights reserved.
