摘要 维生素C生产过程中产生的古龙酸发酵废液中含有较多的氯离子,阻碍了其资源化利用。采用物理法、化学法(醋酸铅法、铜粉法、亚硫酸钠法等)、电化学法等多种方法进行脱除实验。结果表明,亚硫酸钠法效果明显,能将氯离子质量分数从1.88%降至0.08%。 Several methods,such as physical,chemical and electrochemical method,are used to remove chloride ion in gulonic acid fermentation waste generated during Vitamin C production process.The results show that sodium sulfite method can effectively reduce chloride ion from 1.88% (mass fraction) to 0.08% (mass fraction).
