Objective:

2

To optimize the recovery technology for 6 kinds of toxic alkaloids in the toxic wastewater from processing of Aconiti Radix with macroporous resin.

Method:

2

With the rates of adsorption and elution of benzoylmesaconine

benzoylaconine

benzoylhypaconine

mesaconitine

hypaconitine and aconitine as indexes

static and dynamic adsorption-elution tests were used to select the best one from 15 kinds of macroporous resin

and the recovery technology parameters of six toxic alkaloids in the wastewater from processing of Aconiti Radix were optimized.

Result:

2

D101 macroporous resin had a good adsorption and elution effect on 6 kinds of toxic alkaloids in the wastewater from processing of Aconiti Radix

its optimum technology conditions were as follows: each gram of macroporous resin could be used to treat processing wastewater from 4.3 g of Aconiti Radix

the sample loading speed was not higher than 3.0 mL·min

-1

the resin column was eluted with 6 BV of 70%ethanol after removing impurities with 2 BV of water.The recoveries of benzoylmesaconine

benzoylaconine

benzoylhypaconine

mesaconitine

hypaconitine and aconitine were 98.03%

94.09%

96.53%

78.15%

85.40%and 70.57%

respectively.

Conclusion:

2

D101 macroporous resin can be used for detoxification treatment of processing wastewater of Aconiti Radix

at the same time

6 kinds of alkaloids are effectively recovered

which can solve the environmental problems and create certain economic benefits

and the optimized process conditions are stable and feasible.
