The discussion centers on the physical separation of colloids from solutions, exploring methods beyond conventional filtration and membranes. Participants consider various techniques, including coagulation, flocculation, and other physical methods.
Participants express a range of methods for separating colloids, but there is no consensus on the effectiveness or applicability of these methods. The discussion remains unresolved regarding the best approach.
Participants emphasize the importance of minimizing contamination and express varying levels of familiarity with the proposed methods, indicating a potential gap in shared knowledge about their effectiveness.
I want to minimize contamination as much as possible so I want to avoid adding chemicals, that's why I emphasized physical methods. Anyway, thank you for the suggestion!Ygggdrasil said:Coagulation and flocculation can be used to cause colloidal particles to aggregate, which enables their easier removal from a solution (e.g. by filtration).
Interesting, this is the first time that I've heard of these methods. I will explore these ideas more. Thank you!Nik_2213 said:IIRC, you may be able to coagulate / flocculate some colloids 'without' contamination by generating ions in-situ using electrolysis.
Another approach is ultrasound.
YMMV...
