The oxidation states of isotopes of iodine when they recoil as fission fragments from a thin film of irradiated uranium oxide (UO) into potassium sulphate have been investigated. After irradiation the samples were dissolved in excess of iodate and iodide carrier and the radioactivity of the two ...
摘要: Oxidation of As(Ⅲ) in water by iron(Ⅱ)-catalyzed potassium persulfate as well as the influence of various pH and initial concentration of Fe(Ⅱ) was investigated. The potential radicals and possible oxidation mechanism were also studied.关键词:...
7. Potassium Perchlorate (KClO4) The oxidation numbers of potassium (K) and oxygen (O) are +1 and -2, respectively. Let x be the oxidation number of chlorine (Cl). KClO4 is a neutral compound. Therefore, +1 + x + (-2) x 4 = 0 Or, 1 + x – 8 = 0 Or, x = +7 8. Po...
Mean Reactor Cross Sections for (n, p) Reactions on Titanium The Use of Ge(Li) Detectors in Activation Analysis Separation of Carrier-Free 32P from Elementary Sulphur on an Active Carbon Column The pΗ Dependence of the Oxidation States of Recoil 54Mn in Crystalline Potassium Permanganate ...
Cephalosporins in the sulfoxide or sulfone oxidation states can easily be obtained by treatment with different oxidants. This sulfur oxidation is usually accomplished for one of the following reasons: (1) sulfoxide formation to obtain reactive intermediates for further transformations; (2) sulfoxide forma...
Developmental aspects of potassium flux and permeability of the embryonic chick heart. the rate coefficient for 42K efflux was minimal for preparations from 6-8 day old embryos, and distinctly higher values were obtained for the hearts of ... EE Carmeliet,CR Horres,M Lieberman,... - 《Journal...
wastewater is treated in the initial and subsequent ponds and then polished in the final pond. On the contrary, wastewater flow is evenly divided in the parallel pond arrangement. The USEPA states that wastewater flow division normally occurs in the first two waste stabilization ponds (USEPA2011...
The persistent and/or amalgamation type behavior are well classified by magnitude of Δ/W, where Δ and W are the energy difference between divalent and trivalent states and band width of the CN- stretching mode, respectively. Thus, IR spectroscopy is a sensitive probe for the CN- stretching ...
Active phase of a nickel phosphide (Ni 2 P) catalyst supported on KUSY zeolite for the hydrodesulfurization of 4,6-DMDBT Ni 2P catalysts supported on potassium ion-exchanged ultrastable Y zeolites (KUSY) were prepared by temperature-programmed reduction (TPR), and the effect ... YK Lee,Y Shu...
but often can't be distinguished for crystals with the desired size of 20-30 nm. Therefore, in addition to diffraction, we implemented potassium permanganate titration as a simple and quantitative method to monitor the iron II content during oxidation and determine precisely how much oxygen was re...
