Abstract The purpose of this work was to study the effect selenium nanoparticles (Se NPs) on biological and morphofunctional parameters barley seeds ( Hordéum vulgáre L.) We used L. with reduced characteristics. For experiment, Se NPs were synthesized stabilized didecyldimethylammonium chloride. It found that have a spherical shape diameter about 50 nm. According dynamic light scattering data, average hydrodynamic radius particles 28 ± 8 is observed positive ζ-potential (+ 27.3 mV). we treated (1, 5, 10 20 mg/L). experiment showed treatment has best length roots sprout at concentration 5 mg/L number thickness mg/L. Germinability germination energy higher in group NPs. Analysis macrophotographs samples, histological sections 3D visualization by microcomputing tomography confirmed Moreover, no local destructions detected concentrations > mg/L, which most likely due inhibition regulatory catalytic processes germinating seeds. caused significant stress, coupled intensive formation reactive oxygen species, leading reorientation root system growth towards thickening. Based results obtained, it concluded had toxic effect. 5% maximum efficiency allows us further consider as stimulator for development crop under stress

Food dyes with a diverse set of colorants stimulate appetite and enhance aesthetic charm food on table but at the same time these contaminate aquatic biological ecosystems due to their cytotoxic carcinogenic potentials. Herein, we report magnetite catalyzed removal sunset yellow dye from water through catalytic degradation ozonation. The catalyst revealed about 83% 92% ozonation performance toward 100 25 min, respectively. Furthermore, persulphate/magnetite/O3 hybrid system superior compared persulphate/magnetite under identical conditions. Kinetic studies that data followed second-order kinetics, suggesting process is physicochemical in nature. This study further demonstrates persulfate/magnetite/O3 can efficiently decompose aqueous solution Fenton's reagent simple decomposition processes which attributed its unique structural features.
