Catalytic Use of Pd(II) Complex Bearing 2-(thiophen-2-yl)-1H-Benzimidazole Ligand for The Reduction / Degradation of Multiple Mixtures Containing 4-NP, RhB and MB Organic Pollutants

In this study, the catalytic use of [Pd(L1)2]Cl2 complex is aimed for reduction / degradation reactions organic pollutants in water sources which pose a threat to environment. For purpose, 2-(thiophen-2-yl)-1H-benzimidazole ligand (L1) and its Pd(II) (C1) were synthesized characterized by FT-IR, 1H-NMR, 13C-NMR, ESI-MS spectroscopic techniques. The efficiency C1 on 4-nitro phenol compound (4-NP) rhodamine B (RhB), methylene blue (MB) dyes was investigated presence NaBH4 aqueous medium. performance examined with single solutions these substrates (4-NP RhB, MB dyes) at end 5 minutes, over 92% conversion observed all three substrates. trials 4-NP + RhB triple substrate mixture, 84, 94 93% values obtained, respectively, after minutes. catalyst very effective simultaneous toxic compounds from environments without any competition or selectivity.
