本研究主要探討利用丁氧基乙醇(Ethylene glycol monobutyl ether, EGMBE)為修飾劑,二氯甲烷為稀釋劑,二(2-乙基己基)磷酸(D2EHPA)為萃取劑所製成的萃取劑含浸樹脂(EIR) ,在不同的操作條件下,如改變鎂離子初濃度、不同的EIR使用量及改變溫度等,與硫酸鎂水溶液吸附平衡後,其金屬離子之吸附情形,並尋求相同吸附模式。
In this paper, we used the ethylene glycol monobutyl ether, (EGMBE) as the modifier, dichloromethane as the diluents, and D2EHPA as the extractant to prepare the extractant-impregnated resin, EIR. We examined the effects of various parameters, such as the initial concentration of the metal ions, the amount of EIR and the operating temperature. We also investigated the adsorption of Magnesium ions on EIR.
