| 1 | 阀切换循环离子色谱法测定高盐基体中的亚硝酸盐显示文摘建立了一种循环阀切换离子色谱技术检测高盐基体中的亚硝酸盐的方法。通过设置合适的阀切换时间,除去高盐基体中大部分高浓度Cl-,NO2-收集于六通阀中的定量环,经KOH淋洗液进入Dionex Ion Pac AS11-HC (4 mm×50 mm)保护柱和AS11-HC (4 mm×250 mm)分析柱分离后进行电导法检测。实验结果表明,在0. 01~1. 00 mg/L的线性范围内,相关系数r2=0. 9994,相对标准偏差为7. 0%,检出限为2. 67μg/L,所得样品的加标回收率为87. 8%~116. 9%。该方法可用于高盐基体中NO2-的检测。 | 黄雪婷 金小玲 Nesterenko Pavel N 叶明立 陈梅兰 | 2020 | 分析试验室2020,39,11: | 5 |
| 2 | 三种饮用水中主要阳离子的离子色谱法检测及其分布特征显示文摘通过建立的离子色谱-抑制电导法检测天然饮用矿泉水、管网末梢水和地表水水样中主要阳离子(Li+、Na+、NH+4、K+、Mg2+、Ca2+、Sr2+)的浓度,并分析不同类型饮用水中阳离子的浓度水平差异及分布特征。采用IonPac CS16(5 mm×250 mm)分离柱和IonPac CG16(5 mm×50 mm)保护柱,在40℃的柱温下,以30 mmol/L甲基磺酸(MSA)为流动相,流速为1.0 mL/min。结果表明,NH+4在饮用天然矿泉水和管网末梢水水样中均未被检出,地表水中的检出浓度≤1.89 mg/L,Li+和Sr2+的检出浓度普遍较低(Li+≤0.026 mg/L,Sr2+≤0.263 mg/L),检出浓度最高的是Na+和Ca2+。不同类型水样中阳离子检出浓度平均值顺序均为:地表水>管网末梢水>饮用天然矿泉水。 | 周晚晴 Nesterenko Pavel N 林洋 金小玲 黄金飞 叶明立 陈梅兰 | 2019 | 食品工业科技2019,40,24: | 4 |
| 3 | 反相色谱和离子交换色谱测定三聚氰胺氰尿酸中三聚氰胺与硫脲的对比研究显示文摘分别采用反相色谱和离子交换色谱检测三聚氰胺氰尿酸(MCA)中三聚氰胺和硫脲,并对检测方法进行了对比研究。实验分别使用盛瀚SH-CC-4柱,流动相为甲醇∶5mmol·L^-1甲基磺酸(10∶90,V∶V)和AgilentTC-C18柱,流动相为乙腈∶5mmol·L^-1醋酸铵(3∶97,V∶V)为流动相对其进行分离,紫外检测。结果表明,反相色谱法中三聚氰胺在0.5~8.0mg·L^-1范围内线性关系良好,相关系数R2为0.9995,检测限和定量限分别为2.2×10^-3 mg·L^-1和7.5×10^-3 mg·L^-1,方法精密度(重复性)RSD=1.41%(n=7),样品回收率91.3%。硫脲在0.05-0.8mg·L^-1范围内线性关系良好,相关系数R2为0.9993,检测限和定量限分别为2×10^-4 mg·L^-1和7×10^-4 mg·L^-1,方法精密度(重复性)RSD=0.68%(n=7),离子交换色谱法峰形对称,三聚氰胺在0.5~8.0mg·L^-1范围内线性关系良好,相关系数R2为0.999,检测限和定量限分别为1.7×10^-3 mg·L^-1、6.1×10^-3mg·L^-1,分析方法(重现性)RSD=1.12%(n=11),样品回收率95.8%,硫脲在0.5~8.0mg·L^-1范围内线性关系良好,相关系数R2为0.999,检测限和定量限分别为1.6×10^-3 mg·L^-1和5.1×10^-3 mg·L^-1,方法精密度(重复性)RSD=1.5%(n=5)对测定结果的F检验(方法精密度)表明两者无显著性差异,但t检验(方法系统误差)表明两者有显著差异。两种方法均能较好地对样品中的三聚氰胺和硫脲进行定性和定量分析,但两者存在系统误差,原因需进一步探索。 | 叶明立 卢浈乐 Nesterenko Pavel N. 陈梅兰 崔海容 | 2020 | 分析仪器2020,,6: | 2 |
