Determination of acrylic acid and p-phthalic acid in the desizing powder by ion chromatography(离子色谱法同时测定纺织业退浆料中的丙烯酸和对苯二甲酸)
建立了同时测定纺织业退浆料中的2种目标有机酸丙烯酸和对苯二甲酸(PTA)的离子色谱快速检测方法.该方法使用的色谱柱为Thermo IonPac AG11-HC保护柱(4 mm×50 mm)和Thermo IonPac AS11-HC分析柱(4 mm×250 mm), 以氢氧化钾为淋洗液进行梯度洗脱,梯度洗脱过程为0~8 min,10 mmol • L-1 KOH;8.1~18 min, 45 mmol • L-1KOH;18.1~25 min,10 mmol • L-1 KOH,流速为1.0 mL • min-1,采用抑制型电导检测,外标法定量.在优化的色谱条件下,丙烯酸和对苯二甲酸的线性区间...
