摘要

基于淋洗液自动发生技术

建立了用离子色谱测定天然水中F-、CH3COO-、C2H5COO-、HCOO-、Cl-、NO2-、Br-、NO3-、SO42-、PO43-的方法。采用IonPac AS17-C型阴离子分析柱

采用EG40淋洗液自动发生器在线产生KOH淋洗液进行梯度淋洗

淋洗液流速为1.0mL/min

分析柱柱温为30℃

进样量为25μL

测定各离子的检出限分布在0.5～3.1μg/L

相对标准偏差(RSD)小于0.92%;实际天然水样加标回收率总范围为95.2%～101.8%。该方法具有灵敏、快速、准确等优点

适用于天然水中多种阴离子的同时分析测定。

Abstract

Based on eluent autogeneration technology

ion chromatography determination of F-

CH3COO-

C2H5COO-

HCOO-

Cl-

NO2-

Br-

NO3-

SO42-

PO43-in natural water was established.Gradient elution was performed by using the IonPac AS17-C analytical column

and the KOH eluent was online generated by EG40.The flow rate was 1.0 mL/min

column temperature was 30 ℃

and the injection volume was 25μL.Results show that

the ion detection limits are distributed within 0.5～3.1 μg/L

and the relative standard deviation(RSD) is less than 0.92%;test recovery rate for actual natural water sample is from 95.2% to101.8%.Because it is sensitive

fast and accurate

this gradient elution method applies to simultaneous determination of multiple anions in natural water.
