中文摘要 | 氰化銅水溶液中之離子以Cu(CN)□形式存在此n為2,3,4。本研究係提出較為完整之熱力學模式,建立銅(1)物種之組成與分佈,並經由紅外光譜和拉曼光譜儀鑑定,結果發現鹼性氰化銅水溶液(pH>10)中之主要物種為: (Ⅰ)當2<CN/Cu<3時,其主要離子為Cu(CN)□和Cu(CN)□ (Ⅱ)當3<CN/Cu<4時,其主要離子為Cu(CN)□和Cu(CN)□ (Ⅲ)當CN/Cu>4時,其主要離子為Cu(CN)□和CN¯。 |
英文摘要 | The species of cuprocyanide solution are in the forms of Cu(CN)□, where n=2, 3 and 4. A thermodynamic model was established in this study to calculate the compositional distribution of this solution. Qualitative identifications were also carried out by means of infrared and Raman spectroscopy. It was found that for alkaline cuprocyanide solution (pH>10), the major species of the system are: (1) Cu(CN)□, Cu(CN)□, for 2<CN/Cu<3 (2) Cu(CN)□, Cu(CN)□, for 3<CN/Cu<4 (3) Cu(CN)□, CN⁻, for CN/Cu>4 |
