The extraction technology of betaine from waste solution of processing beet by anion and cation exchange resin was studied. The effects of dosage and dropping rate of ammonia on extraction rate of beta-ine were investigated. The orthogonal design was adopted to evaluate the optimization extraction process. The optimum conditions of the extraction are as follows:the concentration of sodium hydroxide solution is 1. 0 mol/L,the concentration of hydrochloric acid is 2. 0 mol/L,the ammonia dosage is 300 mL,the drop-ping rate of ammonia is 1. 75 mL/min.
