    Abstract: 在過去的研究中可以得知若要在逆流型多行程薄膜萃取系統中計算出質量傳送速率,因為計算式中包含了未知的出口濃度,所以計算上必須要使用繁雜的疊代法來求得。
    A modified correction-factor analysis is introduced in present study to develop equations for estimating the mass-transfer rate in multipass backward-flow membrane extractors, in which the unknown solute outlet concentrations are neither in the estimating equation nor in the modified correction-factor charts, and thus the calculation is easy and direct without using the try-and-error method that should be employed in the conventional correction-factor analysis. Experimental results confirm the prediction values for the extraction of acetic acid from aqueous solution by methyl isobutyl ketone in a double-pass device.
