利用碘-131標誌追蹤法研究鉑黑吸附劑對碘吸附之特性與條件,本實驗自行研製之鉑黑對碘之吸附量為最高,每克鉑黑吸附5.55毫克碘,擔體碘化鉀,吸附液硫酸濃度,吸附平衡時間及溫度等對吸附均有影響,試驗工作中獲得吸附最佳條件。
By means of labeled Iodine-131 to study the relationships between the absorbent of platinum black and Iodine, the highest adsorption capacity of self-made platinum black to Iodine, i. e. 5.55 mg Iodine/g-platinum black was achieved. The adsorption efficiency was influenced by carrier potassium iodide, concentration of sulfuric acid, time of adsorption and temperature. The optimum condition has gained from experimental work.
