Abstract:  The adsorption behavior of apple juice patulin with eight kinds of macroreticular adsorption resins was investigatedin the work. The optimum kinds of macroreticular adsorption resins were selected. The isotherm of LSA-800B macroreticular adsorption resin and its static and dynamic kinetics were both studied, and the optimum parameters of adsorption were procured. It was shown that the equilibrium time of LSA-800B macroreticular adsorption resin for patulin was 3h. The isotherm of LSA-800B macroreticular adsorption resin at 20℃ could be described by Freundlich isotherm. The flow rate, temperature and concentration of patulin in apple juice affected very much the kinetic curves of LSA-800B macroreticular adsorption resin to patulin. The optimum conditions were: 4BV/h and 50℃.
