pH controlling unit for controlling equilibrium pH during stripping of D2EHPA (1 reply and 1 comment)

Dear all, 

I have a loaded D2EHPA phase with Cu, Co and Li and want to selectively strip them by controlling the equilibrium pH (with H2SO4 mainly). I have some selectivity but I want to increase it by using multiple counter current stages in a mixer settler. Only thing that remains difficult is how to control the equilibrium pH. We only have pH meters and mixer settlers. So I was wondering if somebody here could advice me pH controlling unit that I could use for this. Would be ideal that there is a pH meter and an unit that controls the pump of a base or acid to control and keep the pH steady after each stage.

Can someone help me please?

Very big thanks in advance,

Nand
