中文摘要 | 鈾(VI)與2-呋喃甲酸(HFC)之錯化物在極譜上溫度25±0.1℃,pH範圍從1.2到4.9,及ligand濃度從0.025M到0.200M被探討。在pH<2.5,兩種UO□和UO₂‧FC‧HFC⁺被還原而形成一種三步驟之極譜波。在2.5<pH<4.3 UO₂(FC)₂之似可逆波被獲得: UO₂(FC)₂+ e ⇄ UO₂FC+ FC¯¹。藉著修飾Koutecky方程式求得動力學的參數。在pH>4.3,有UO₂(CH)FC之還原波。由於ligand之吸附所產生的反常波,被證實為加速波達到極限電流,但不影響擴散電流和汞高度之關係i□=kh□。 |
英文摘要 | The complexation of uranium (VI) with 2-furancarboxylic acid (HFC) was studied Dolarographically over the pH range 1.2 to 4.9 with the ligand concentrations varying from 0.025M to 0.200M at 25±0.01℃. At pH<2.5, two species, UO□ and UO₂.FC.HFC⁺ were reduced to form a thee-step polarographic wave. Between pH 2.5 and 4.3, a quasi-reversible wave of UO₂(FC)₂ was obtained: UO₂(FC)₂+ e ⇄ UO₂FC+ FC⁻¹. The kinetic parameters were determined with a modified Kontecky equation. At pH>4.3, there was a reduction wave of UO₂(OH)FC species. The abnormal waves due to the adsorption of ligand, were proved to accelerate the wave to reach the limiting current and do not influence the relation between diffusion current and mercury height, i□=kh□. |
