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。
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.
