摘要
以2 mmol/L的NaOH溶液为阴离子萃取剂、1%(体积分数)乙酸溶液为阳离子萃取剂,采用离子色谱法分测定了14种卷烟纸样品中的7种阴离子和4种阳离子。结果表明:7种阴离子的回收率在90.00%～104.67%之间,相对标准偏差在0.47%～3.50%之间;4种阳离子的回收率在96.00%～105.00%之间,相对标准偏差在0.63%～2.08%之间。
14 kinds of cigarette paper were extracted with 2 mmol/L sodium hydroxide solution and 1% （volume fraction） acetic acid solution. 7 kinds of anions and 4 kinds of cations were determined by ion chromatography. The results indicated that： the recoveries of anions were from 90.00% to104.67% , with RSD of 0.47 % to 3.50% ; the recoveries of cations were from 96.0% to105.00% , with RSD of 0.63 % to 2.08%.
