The effect of supplying either nitrate or ammonium on nitrate reductase activity (NRA) was investigated in Brassica napus seedlings. In roots, nitrate reductase activity (NRA) increased as a function of nitrate content in tissues and decreased when ammonium was the sole nitrogen source. Conversely, in the shoots (comprising the cotyledons and hypocotyl), NRA was shown to be independent of nitra...
Oxidation of Methyl Orange (MO) solution in potassium peroxydisulfate (KPS) homogeneous reaction system without UV irradiation was investigated. The result shows that decolorization of MO increases as the dosage of K2S2O8 increases. The kinetic results demonstrate that the decolorization reaction is a pseudo first-order reaction when the concentration of MO ...
conclusions based on nitrification and denitrification data, the best condition for nitrifying/ denitrifying performance was obtained by modified-ifas. hence, the modification can be used to obtain the best activities of microbial and nitrogen removal improvement. results employing the bet, surface area (sa), total pore volume (vp), and average size of the nanostructure were 0.4026 m2/g, 3.8089...
Nowadays, the nature of active species and role peroxydisulfate (PDS) was still unclear in advance oxidation systems based on activation PDS by CuO with non-radical pathway. In this paper, a sheet like containing two kinds Cu2+ prepared, one which electron deficient (Cu2+-h). The CuO/PDS system showed extraordinarily utilization (172.3%) for BPA degradation (after four cycles PDS). main mechani...
