| 摘 要： | 建立了用离子色谱测定4,6-二羟基嘧啶产品中残留甲酸含量的新方法。淋洗液为3mmol／LNaOH，流速1．5mL／min．抑制器为ASRS-ULTRA，抑制电流50mA，自循环模式。甲酸在0.3636～7.272mg／L时，峰面积与样品浓度有良好的线性关系(y=0.2101x 0．0157，r=0.9995)，检测限为0．001mg／L。方法简单实用。

| Abstract: | A new method to analyse methane acid in 4,6-dihydroxypyrimidine was established .A solution containing 3mmol/L NaOH was used as eluent on an AS11-HC column. The flow rate is 1.5ml/min. The self-regenerating suppressor current is 50mA. The methane acid linear equation was y=0.210x+0.0157, correlation coefficient was 0.9997. The method is rapid and simplicity. |
