Abstract In an attempt to create wastewater treatment “green” techniques that are both economically feasible and sustainable without using any dangerous chemicals, barley grain ( Hordeum vulgare L.) water extract was used phyto-synthesize silver nanoparticles (Ag°). Barley grains served as a natural reductant stabilizer at the same time. The role of different synthesis conditions their effect on efficiency green process were studied confirmed with characterization several (UV–vis, SEM, EDX, sizing distribution, FTIR). Ag°9 formula catalytic reduction inspected against p- nitrophenol (PNP) methylene blue (MB) model nitroaromatic components dyes, respectively. removal studies conducted target pollutants in single or mixed liquid state. Remarkably, particle size around 20 nm, its final concentration current 2.2 × 10 −7 mol L −1 . adsorption mechanism PNP MB pseudo-second order. good fit pseudo-second-order kinetic suggests chemisorption occurs sorption process. activity remove 99 66% levels 60 500 µL from formula, respectively, within less than 5 min.
