Fabrication of Luminescent Microtiterplate Using Terbium Complex for Phenol Screening in Seawater Samples

Tb(III)-2-aminoterphthalate complex Tb₂-(ATPh)₃ was synthesized and characterized using FT-IR, thermal analysis and elemental analysis. Tb₂(ATPh)₃ microtiter plate was fabricated through embedding Tb(III) complex in polyvinyl chloride membrane and used for environmental determination of phenol in sea water samples. The calculated detection (D_L), quantification (Q_L) limits, and binding constant (K_D) were 00.63 µmol L^- 1, 2.10 µmol L^- 1 and 1.32 × 10⁴ mol^- 1 L, respectively. The fabricated microtiter plates exhibited high selectivity towards phenol over other hydrocarbon compounds. Furthermore, AGREE metric tool was used to assess the method's green nature as well as its practicability and applicability. These merit outcomes provide that the new method for phenol detection was environmentally benign and safe to humans. The prepared Tb₂(ATPh)₃ MTP was validated through using gas chromatography for monitoring phenol in Suez Bay water accurately with high precision. The obtained results encouraged using Tb₂(ATPh)₃ MTP for efficient, fast, selective, and direct screening of phenol in real samples.
