| Summary, etc. | Amberlite IRA-400 anion exchange resin was applied for the recovery of l-(+)-lactic acid from fermentation broth. Adsorption isotherm and breakthrough curves for the separation of l-(+)-lactic acid were obtained at pH 5.0 and 2.0, respectively. Different types of adsorption isotherms were found at pH above and below the pKa (3.86)of lactic acid. The isotherm was found to be a Langmuir type at pH 5.0, whereas t e isotherm was type II (multilayer adsorption)at pH 2.0. At pH 5.0, the maximum adsorption capacity of the resin, qm and dissociation constant,Kd were 222.46 mg/g wet resin and 60.7 mg/ml, respectively. Breakthrough curve for the separation of lactic acid from fermentation brothwas also obtained. The maximum adsorption capacity (197.09 mg/g wet resin)at pH 5.0wasmuch higher than that at pH 2.0 (106 mg/g wet resin). Proper elution and washing conditions were sought by using H2SO4, methanol, ammonia or their mixtures as eluant. When column separation was performed at pH 5.0 by using 50 |
