Analysis of Cations in Drinking Water and Wastewater, Conforming to ASTM D6919-03

User Benefits

- Data with good linearity and repeatability can be obtained in analysis conforming to ASTM D6919-03. - Cations in drinking water and wastewater can be quantified. - Separation of sodium and ammonium ions can be improved by adding 18-crown-6 ether to the mobile phase.

Introduction

Ion chromatography can be widely employed for the detection and quantification of ionic components in aqueous solutions. ASTM D6919-03, published by ASTM International, USA, specifies an ion chromatographic method for analyzing the six cations (lithium, sodium, ammonium, potassium, magnesium, and calcium ions) in drinking water and wastewater. This article introduces analysis of the six cations in drinking water and wastewater using non-suppressor ion chromatograph that conforms to ASTM D6919-03.
