| 摘要: Pr(Ⅳ)碱式碳酸盐能溶于一定pH值和浓度的丙二酸水溶液中,形成黄色丙二酸镨(Ⅳ)配合物。该配合物溶液在265nm附近有一特征宽带吸收峰。测得配合物组成比Pr(Ⅳ):CH2(COO)2-=1:2。Pr(Ⅳ)的自还原动力学研究表明为拟一级反应。 |

| Abstract: Pr(Ⅳ) basic carbonate is dissolvable in squeous solution of malonic acid to yield an yellow Pr(Ⅳ)-CH2(COO)22- complex which shows abroad characteristic absorption band at 265 nm. The complex composition ratio of Pr(Ⅳ)-CH2(COO)22- determined by equilibrium shift method is 1:2. It has been found that the reduction kinetics of Pr(Ⅳ)-CH2(COO)22- complex in aqueous solution is pseudo first order reaction for Pr(Ⅳ) |
| Keywords: Pr(Ⅳ) malonic acid complex pseudo first order reaction. |
