Effect of cationic counter ions on the critical concentration for phase separation.

Inorganic counter ions		Organic counter ions
Suspension	Critical concentration for phase separation (%)	Suspension	Critical concentration for phase separation (%)
S-H	4.9	S-H	4.9
S-Na	5.3	S-NH4	5.2
S-K	5.4	S-Tri-MA	5.5
S-Cs	5.9	S-Tri-EA	6.0

S stands for sulfate which came from hydrolysis of cellulose using sulfuric acid. In her 1996 paper, the effect of NaCl and KCl salts on phase separation of cellulose crystallites was used.
