The regenerating solution may be an acidic solution.

Further, the method includes contacting the intermediate solution with an acid to form an acidic solution.

Described herein is a physiologically-balanced, acidic solution.

Described herein is a physiologically balanced, ionized, acidic solution, typically prepared by the electrolysis of a solution comprising a mixture of inorganic salts in physiologically balanced proportions.

The glucosamine is then separated from the acidic solution.

The scrub solution feed stream comprises an acidic solution of sodium fluoride.

The acidic solution comprises a metal salt and water.

Also disclosed is a bleaching system for forming the acidic bleaching solution, as well as a method of preparing the acidic bleaching solution.

The Bi-212 is then eluted from the extraction medium with an acid solution to form a substantially radio-impurity-free Bi-212 acid solution.

Blow through any remaining acid solution with a stream of air.

The surface of the base is covered by an acidic solution.

An aqueous acid solution (21) is placed in the column (61).

The production of scale in an acidic environment is difficult because of the acidic solution neutralizing most known inhibitors.

The alcohol additive is selected from methanol, ethanol and glycerol, and the acid solution comprises phosphoric acid.

The acid solution is warmed up to an elevated temperature by bringing off-gas of the leaching step into direct con¬ tact with the acid solution.
