Abstract: 001×7 strong-acid cation exchange resin was used to remove the harmful heavy metal ions Pb2+, Cd2+ and Cu2+ in the Chinese
herb extract, and the recovery of flavonoid was also detected. The results showed that 001×7 strong acid cation exchange resin was of great
efficiency for the removal of Pb2+, Cd2+ and Cu2++ in the Chinese herb extract, and the recovery of flavonoid was ~%. 001×7
strong-acid cation exchange resin had a large adsorption capacity. 10 ml Wet exchange resin could adsorb mg Pb2+, mg Cu2+, or
mg Cd2+, respectively.
Key words: ion exchange resin; heavy metal ions; Chinese herb extract; flavonoid content
