摘要
为明确电渗析对烟梗提取液中主要盐类物质的影响,考察了电渗析对烟梗提取液4种无机酸盐(氯化物、硝酸盐、硫酸盐和磷酸盐)、3种金属盐(钾盐、镁盐和钙盐)及3种有机酸盐(苹果酸盐、草酸盐和柠檬酸盐)的脱除效果。结果表明:电渗析对不同的盐类物质脱除效果有差异,氯化物、硝酸盐和钾盐脱除较快。无机酸盐、金属盐和有机酸盐的脱除速率大小顺序分别为:氯化物>硝酸盐>硫酸盐>磷酸盐,钾盐>镁盐>钙盐,苹果酸盐>草酸盐>柠檬酸盐。利用电渗析在调控烟梗提取液中氯含量的同时,也可以降低其硝酸盐含量,进而实现对再造烟叶产品氯和硝酸盐指标的调控。
In order to find out the effects of electrodialysis（ED） on the major salts in tobacco stem extract,the removal efficiencies of ED for four inorganic acid salts（chloride, nitrate, sulfate and phosphate）, threemetallic salts（potassium salt, magnesium salt and calcium salt） and three organic acid salts（malate, oxalateand citrate） were investigated. The results showed that： the removal efficiencies of ED for different kind saltsdiffered, chloride, nitrate and potassium salts were removed more quickly; the order of removal rates for fourinorganic acid salts was chloride 〉nitrate〉 sulphate 〉phosphate, for three metallic salts was potassium salt 〉magnesium salt 〉calcium salt, and for three organic acid salts was malate〉 oxalate〉 citrate. Byregulating both chloride content and nitrate content in tobacco stem extract, ED further regulated thecontents of chlorine and nitrate in reconstituted tobacco.
