| 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 95.3~97.9%.001×7 strong-acid cation exchange resin had a large adsorption capacity.10 ml Wet exchange resin could adsorb 58.7 mg Pb2+,19.04 mg Cu2+,or 33.68 mg Cd2+,respectively. |
