In this study, a new palladium nanocatalyst (GA-Sch-Pd) was prepared derived from modified gum arabic and characterized by FT-IR, TGA, FE-SEM, EDS, TEM, and XRD analyses. Then, the catalytic potential of GA-Sch-Pd nanocatalyst was tested in the catalytic reductions of different organic pollutants such as o-nitroaniline (o-NA), p-nitrophenol (p-NP), p-nitro-o-phenylenediamine (p-NPDA), p-nitroaniline (p-NA), congo red (CR), methylene blue (MB), and methyl orange (MO) by using NaBH4 in water. These tests showed GA-Sch-Pd nanocatalyst had high activity against reduction of nitroarenes and organic dyes at very short reaction durations. Moreover, GA-Sch-Pd nanocatalyst was easily separated and reused for several times. This study shows that GA-Sch-Pd nanocatalyst has a high potential for remediation of environmental pollutants in wastewaters.enAttribution-NonCommercial-NoDerivs 3.0 United Statesinfo:eu-repo/semantics/closedAccessDyesNitroarenesPalladiumReductionArticle161---10.1016/j.ijbiomac.2020.07.32132791268Q1WOS:000569754200009Q1
