Was wondering if any one had a good flocculant to use in a lye solution. I know their are brand name flocculants you can buy off the shelf but was wondering if any one could recommend a decent flocculant that you can make at home? Iv seen mention of aluminum chloride or iron sulfate but am not sure. Looking to help coagulate hydroxides from a sodium hydroxide solution that was used to strip soder mask from some pcb boards, expect most hydroxides present to be tin and lead. Any thoughts would be appreciated.
Home made Flocculant for lye solution anybody?
