摘要：

Ultrasound radiation has been studied as a possible novel parameter to control ion-exchange chromatographic retention of some simple ions. Though the reason has not been elucidated, ultrasound radiation has reduced the retention for the larger and less solvated ions but enhanced the retention of the smaller and more solvated ions. The adsorption amounts of weak acids have been also affected by ultrasound radiation. (C) 1998 Elsevier Science B.V.
