hydrazine sulfate, ketazine, and dialkyldiazacyclopropane. Hydrazine also is used as a start-up ingredient in the preparation of cooling water for nuclear reactors where it is desired to keep the oxygen content of the water to an absolute minimum and thus decrease corrosion. Oxygen reacts with...
Hydrazine hydrate is prepared by treating hydrazine sulfate, N2H4•H2SO4 with sodium hydroxide. The product is collected by distillation under nitrogen. It also is obtained as a by-product in the Bayer Ketazine process for producing hydrazine in which hydrazine solution is hydrolysed under pressure...
2,4-Dinitrophenylhydrazine immobilized on sodium dodecyl sulfate (SDS)-coated magnetite and was used for removal of Cd(II) and Ni(II) ions from aqueous solution. The prepared product was characterized by X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FT-IR), and ...
The colored complex of [Fe(Bpy)3]2+ was formed in sodium dodecyl sulfate (SDS) as micellar media, and then monitored at 520 nm. The results showed that simultaneous determination of HZ, TSCZ and PHZ could be performed in their concentration ranges of 1.0–70.0, 0.2–6.0 and 0.1–10.0 ...
Nitric oxide (NO) was freshly prepared by mixing 5 ml of anoxic 1.2 m ferrous sulfate in 1.8 m H2SO4 with 3 ml of anoxic 1.2 m sodium nitrite in a syringe inside of the glove box, followed by washing of the resulting colorless gas through 1 m anoxic NaOH to remove NO2 impurities....
The methods are based on the difference observed in the rate of iron (III) reduction with HZ and INIH, in the presence of 2,2′-bipyridine (Bpy) and the subsequent complex formation between the resulted Fe2+ and Bpy in a solution containing sodium dodecyl sulfate (SDS) as a micellar ...
In this study, a new approach for flow injection amperometric detection of N2H4 is proposed based on its electrocatalytic oxidation at a bis(neocuproine)copper (II) chelate complex/sodium dodecyl sulfatemodified graphite pencil electrode (Cu(II)-Ncp/SDS/GPE). The proposed electrode was prepared...
