Biogenic and chemically synthesized Solanum tuberosum peel-silver nanoparticle hybrid for the ultrasonic aided adsorption of bromophenol blue dye.

摘要: This work was aimed at the synthesis of a hybrid (STpe-AgNP), obtained by impregnation silver nanoparticles (AgNP) onto Solanum tuberosum peel (STpe), for ultrasonic assisted adsorption bromophenol blue (BB) dye. SEM, FTIR, XRD, EDX, TGA and BET techniques were used to characterize adsorbents. The SEM EDX confirmed successful AgNPs STpe form hybrid. impregnated found be water stable various pH values 2.0-9.0. Chi-square (χ2   0.996) showed that Freundlich model best fitted among isotherm models, corroborated oriented site model. Kinetic analysis conformed intraparticle diffusion pseudo-first-order rate equations, while thermodynamics displayed physical, spontaneous endothermic process. presence competing Pb(II), Ni(II), Cd(II) Zn(II) metal ions in solution interfered with BB biosorbents. In terms reusability, STpe-AgNP desorption 91.3% 88.5% respectively, using NaOH as eluent. Ultra-sonication significantly enhanced both adsorbents, but only slightly improved dye from simulated wastewater. study also illustrated pristine biomass waste is cheap viable option decontamination water.
