It depends on the composition of solution. If there is macromolecule like protein which you want use in cell culture then I would suggest two methods. 1. Dialysis and 2. Desalting by gel permeation chromatography.
i do support the answer of Parab, dialysis is the most common method, but the compostion of your solution will determine if gel permeation chromatography will be more ideal
Or, maybe you can try cation exchanger if you just wanna remove the Al3+.
Thank you for all of you.
dear Shailesh Parab,dialysis is good method and I would try it but I don't have any information about the second method and Mr Muhammad Radifar I'm going to remove both component of aluminium and sulfate not just aluminium.
I recognize that most of the aluminum precipitate as it accumulates the other components. If some aluminum remain in solution finally ,it can remove by reducing the pH to 6.7-7.4 because in this pH, Al(OH)3 sediment which remove the Al3+ but what about (SO4)2-? how can I remove it?
Finally if other aluminium remain,dialysis is the best way to rid of aluminium.
So what is this other components? Dialysis can remove both Al3+ and SO42-, but you have to be sure that the other component is not small enough to pass through the dialysis membrane. That's why Mr. Parab and Mr. Ogundolie asking the composition of your solution. For example, if you're planning to use 1 kDa membrane dialysis, then you have to be sure that the other component size is larger than 1 kDa.
Thank you dear Muhammad Radifar.
my main component is gelatin,of course it is macromolecules and no need to be worry about it!
