烟梗提取液中氯离子的电渗析法脱除

摘要

In order to study the feasibility of regulating chlorine content in paper-making process reconstituted tobacco (RT) with eletrodialysis (ED), the efficiency of ED for removing chlorine ions from tobacco stem extract was investigated. Five RT samples were prepared with dechlorinated tobacco stem extract, their routine chemical components were analysed, and sensory quality was evaluated. The results showed that: 1) The chloride ions in tobacco stem extract were efficiently removed by ED with the removal rate of more than 99%. 2) The chlorine in RT products could be regulated via removing the chlorine ions in tobacco stem extracts with ED, and the sensory quality of RT products was improved to a certain degree. ED features the advantages of good chlorine removing effect and low material loss, it is suitable for regulating the chlorine content in RT products.%为研究电渗析法调控造纸法再造烟叶氯含量（质量分数，下同）的可行性，考察了电渗析对烟梗提取液氯离子的脱除效果，利用脱氯的烟梗提取液制备了5个再造烟叶试样，并对样品进行了常规化学成分分析和感官质量评价。结果表明：①电渗析法可高效脱除烟梗提取液的氯离子，脱除率可达99%以上；②通过脱除烟梗提取液中的氯离子可调控再造烟叶产品中氯含量，使产品的感官质量得到一定改善。电渗析法具有可调控性强、物料损失小等优点，适用于再造烟叶产品中氯含量的调控。
