摘要

目的：

探讨5种常用絮凝剂对川乌炮制废水中6种生物碱类成分的去除效果。

方法：

采用HPLC测定絮凝处理前后川乌炮制废水中6种生物碱类成分，流动相乙腈-四氢呋喃(25∶15，A)-0.1 mol·L

－1

乙酸铵水溶液(每1 L含冰乙酸0.5 mL，B)梯度洗脱(0～48 min，15%～26%A；48～49 min，26%～35%A；49～58 min，35%A；58～65 min，35%～15%A)，流速1.0 mL·min

－1

，检测波长235 nm。比较三氯化铁、硫酸铝、聚合硫酸铁、聚合氯化铝/聚丙烯酰胺(PAC/PAM)和聚丙烯酸钠5种常用絮凝剂对这6种生物碱类成分的去除特性和效果，并进行了初步工艺优化。

结果：

5种絮凝剂对不同类型的生物碱具有一定的选择性，6种生物碱的去除呈现明显的差异，其中PAC/PAM的减毒作用相对优越，在pH 6，PAC/PAM投加量为0.25 g·L

－1

，PAC-PAM(30∶1)时，川乌炮制废水中的乌头碱类成分综合去除效果较佳，其中新乌头碱去除率85.4%，次乌头碱去除率58.3%。

结论：

絮凝法仅可作为一种前处理工艺，初步实现对川乌炮制废水的减毒处理。

Abstract

Objective:

To investigate the removal effect of 5 kinds of common flocculants on 6 kinds of toxic alkaloids in processing wastewater of Aconiti Radix.

Method:

HPLC was employed to determine contents of 6 kinds of alkaloids in the processing wastewater of Aconiti Radix before and after flocculation.The mobile phase consisted of acetonitrile-tetrahydrofuran(25∶15)-0.1 mol·L

-1

ammonium acetate solution(each 1 L contains 0.5 mL of glacial acetic acid) for gradient elution

volume flow rate was 1.0 mL·min

-1

detection wavelength was 235 nm.The removal characteristics and effects of five common flocculants of ferric chloride

aluminum sulfate

polymeric ferric sulfate

polyaluminum chloride/polyacrylamide(PAC/PAM) and sodium polyacrylate were compared and preliminarily optimized.

Result:

The 5 kinds of flocculants had certain selectivity for different types of alkaloids

and the removal of 6 kinds of alkaloids showed obvious differences.Among them

the PAC/PAM attenuated relative superiority

when the pH 6

adding amount of 0.25 g·L

-1

and PAC-PAM dosing ratio of 30∶1

comprehensive removal effect was relatively good

removal rates of mesaconitine and hypaconitine was 85.4%and 58.3%

respectively.

Conclusion:

The flocculation method can be used as a pretreatment process to reduce the toxicity of processing wastewater of Aconiti Radix.
