Inline copper extraction and phase separation.[a] Inline graphic

Entry Purification Cu content [ppm]
Crude mixture from module 2 n.a. 4720
Extracted org. phase 1 extraction 14.3
Extracted org. phase 3 extractions 6.3

[a] Crude mixture from module 2 and NH3 (32 wt %) aqueous solution was pumped by syringe pump and mixed together in a T‐mixer. A Zaiput membrane separator was connected at the end of the 5 mL PFA extraction coil. Organic phase was checked for Cu content by ICP‐OES analysis.
