摘要: For the first time, the effect of electroendosmosis (EEO) flow phenomenon was investigated in detail, on the gel electromembrane extraction (G-EME). When electric field is used as an actuator of ion transport in G-EME, the EEO flow phenomenon can occur within the agarose gel membrane interface and is generally considered the dominant issue. In this regard, various agarose-based gel membrane types with low-, medium-and high-EEO were fabricated and tested. To further diminish the EEO effect, the different gel membrane …
