【 摘 要 】

References(10)Cited-By(3)A continuous rotating annular chromatograph with rotating inlet and outlet can be used to concentrate a single component by the technique of cycling zone adsorption.To evaluate the performance of this system, an amino acid (valine) was chosen as the solute and a cation exchange resin as the adsorbent. The adsorption force of valine on the cation exchange resin in the eluent (pH = 4.4 or 7.6) became much weaker than that in the feed (pH = 3.4).Experimental elution curves were in good agreement with numerical solutions. The two concentration profiles at steady state agreed very well with each other for 8 and 48 hours after starting the operation of the device. When products were collected over a long period, concentrated products with six times the feed concentration could steadily be obtained.
