翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Hydrodynamic technique ： ウィキペディア英語版 Hydrodynamic technique Hydrodynamic technique is a subcategory of electroanalytical methods in which the analyte solution flows relative to a working electrode. In many voltammetry techniques, the solution is intentionally left still to allow diffusion controlled mass transfer. When a solution is made to flow, through stirring or some other physical mechanism, it is very important to the technique to achieve a very controlled flux or mass transfer in order to obtain predictable results. These methods are types of electrochemical studies which use potentiostats to investigate reaction mechanisms related to redox chemistry among other chemical phenomenon.〔Bard, A.J.; Faulkner, L.R.

Harcourt Brace College Publishers, 1998 ISBN 0-03-002078-6.〕 == Structure == Most experiment involve a three electrode setup but the configuration of the setup varies widely. All cell configurations create a laminar flow of solution across the working electrode(s) producing a steady-state current determined by solution flow rather than diffusion. The current resulting can be mathematically predicted and modeled. Among the most common hydrodynamic setup involves the working electrodes rotating to create a laminar flow of solution across the electrode surface. Both rotating disk electrodes (RDE) and rotating ring-disk electrodes (RRDE) are examples where the working electrode rotates. Other configurations, such as flow cells, use pumps to direct solution at or across the working electrode(s). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hydrodynamic technique」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
