Abstract

Research on PCB-138 treatment is always urgent, along the development of nanotechnology has created general conditions to apply them in this treatment process. With low cost and easy synthesis of Fe/Cu and Fe/Ni bimetallic nanoparticles, the hydrodechlorination (HDC) reaction was conducted to convert PCB-138 in aqueous media into non-toxic or less toxic products. The study results revealed that the optimal conditions for achieving high PCB-138 conversion efficiency were: [Fe/Cu] = 2,0 g/L,  pH = 3; [Fe/Ni] = 2,0 g/L, pH = 7, with a reaction time of 120 to 180 min required to reach adsorption equilibrium. Experimental data indicated that the adsorption of PCB-138 followed a pseudo-second-order kinetic model, confirming a chemisorption mechanism on the surface of the catalytic nanoparticles. Furthermore, the conversion pathway of PCB-138 was proposed, involving the formation of less toxic products such as biphenyl, thereby demonstrating the efficacy of the HDC reaction. This study highlights the practical potential of bimetallic nanoparticles in treating water contaminated with chlorinated organic compounds.
