Procedure
The yield from the ion exchange column is about one liter of hydrogen styrene sulfonate, which is then neutralized by addition of LiOH-H2O powder (approximately 33 g) until the pH of the solution is about 7. The resulting solution of lithium styrene sulfonate in water is dried. A yield of about 143 g lithium styrene sulfonate (a white or grey powder) with a water content of about 9.9% is obtained.
