The reaction process is traced by monitoring the pH value

the variation of pH during carbonation versus of concentration and packing rotating speed is studied and Carbonation mechanism is analyzed combining pH value vaziation and reaction dynamics. Based on reaction of sodium aluminate solution and carbon dioxide gas in rotating packed bed reactor Carbonation Mechanism is investigated. Rotating packed bed reactor quicken the reaction proceedure and shorten the carbonation reaction time. Mass is precipitated during the midreaction time

which is the best time for controlling Al(OH)\-3 particle size.
