The absolute second-order rate constant for the reaction Na + O3→NaO + O2(k1) has been determined by time-resolved atomic resonance absorption spectroscopy at λ= 589 nm [Na(32PJ) Na(32S1/2)] following pulsed irradiation, coupled with monitoring of O3 by light absorption in the ultra-vi...
For instance, Ru metal in acid media loses most of its activity after the first cycle of reaction and completely dissolves within the first 10 cycles, due to metal oxidation when the potential rises42. RuO2 also presents high OER activity but suffers from corrosion after the first cycle; it...
After 30 min, a new absorbance peak at 213 nm appeared and its intensity increased with increasing the reaction time, suggesting the production of a new kind of intermediates dur- ing the reaction31. However, if N2 instead of air was used, a totally different evolution of the UV-Vis ...
under various acid types (HCl, H2SO4, and HNO3) and acid/CFA ratios (5–25 mLacid/gCFA). High product purity (up to 97%) was achieved with HCl (20%wt), and acid/CFA ratio of 20 mLHCl/gCFA. The treated CFA was then converted to zeolite by the fusion reaction under various Si/...
The sticking coefficient of N2O5 on NaCl aerosol α=0.032±0.003 is determined at 292.3±0.5K and various relative humidities, considering the decrease of the aerosol diameter during the reaction. The rate constant ratio for the consecutive chemical reaction leading to ClNO2 (a) or 2 HNO3 (b...
Keywords:Collision cell reaction；ICP-MS；Na；K；Ca；Cigarette paper 卷烟纸是卷烟重要组成部分，卷烟纸的燃烧性能直接而影响卷烟抽吸品质，可通过添加K和Na盐等助燃剂实现卷烟纸燃烧性能的调节，而碳酸钙是卷烟纸生产过程常用的填料,可实现卷烟纸透气度和克重的调节口幻。由此可见，快速测定卷烟纸中K、Na和Ca对...
