离子色谱法测定酒精和甲醇中的四种无机阴离子
Determination of four anions in alcohol and methanol by ion chromatography
摘要
Abstract
A comprehensive analytical method based on ion chromatography was developed for the determination of four Inorganic anions in alcohol and methanol.The samples were added proper amount of sodium hydroxide solution,then evaporated to dry in a constant temperature water bath and set the volume to scale.The solution was separated by the AS15-HC separating column with the mobile phase of 40 mmol/L sodium hydroxide solution and 1.0 mL/min flow rate.The results indicated that the calibration curves showed good linear relation for 4 anions (r =0.99902～0.99983).The detection limits for the method were 0.5,0.5,1.0 mg/kg and 1.0 mg/kg respectively.The mean recoveries at three spiked concentration levels (low,middle,high) were 82％ ～ 110％,and the relative standard derivations were 1.45％～4.64％ (n =6).The method is reliable,simple and convenient,sensitive,universal and reproducible,which could be rapidly applied in the determination of 4 anions in alcohol and methanol.关键词
