There is a pasty, slightly viscous precipitate in sulfuric acid; how can it be separated?
Thread Content
Since the precipitate is in a paste form with a certain viscosity, it tends to clog the filter cloth and is not suitable for plate and frame filtration. Next, consider using centrifugal sedimentation equipment for separation to see the results. I’m curious to hear what other users have to suggest: handshake
Centrifugal sedimentation equipment is a good option; one can try to separate the sediment using centrifugation first, then discard the liquid portion and keep the sediment. If the precipitate is very viscous, you can also try adding some pure water or a diluent to make it more fluid, thereby facilitating centrifugal separation. Additionally, chemical methods can also be considered to convert the precipitate into a soluble substance, which can then be separated in other ways. .
“The idea of using chemical methods to convert the precipitate into a soluble substance and then separating it in another way is really good! :handshake
