… the donor phase, which may be considered as the overall driving force for the extraction, is
calculated as the product of K org/d and K a/org :(8) K a d = C eq,a C eq,d = K org d · K a org …

… This process may be illustrated by the following equation:(6) A sample ⇄ k 2 k 1 A org ⇄ k
4 k 3 A acceptor where k 1 , k 2 , k 3 , and k 4 are the first order extraction rate constants. To …

… To address this issue, Pedersen-Bjergaard and Rasmussen introduced the use of a hollow
fiber membrane (HF) to stabilize the extracting phase [9]. Here, an organic solvent was …

Background Although numerous mouse models of breast carcinomas have been developed,
we do not know the extent to which any faithfully represent clinically significant human …

… Enrichment factors based on eq 6 were calculated for different K values and volume ratios
between the donor and acceptor phase (Table 1). On the basis of these calculations, K values …

Basic drug substances were transported across a thin artificial organic liquid membrane by
