A spike-recovery study was performed under these conditions and satisfactory recoveries between 85.3 and 103.9% for all studied anions were obtained. The determination of common inorganic anions in environmental waters, such as wastewater and drinking, ground, and surface waters, is one of the most important applications of ion chromatography (IC) worldwide. “4110 DETERMINATION OF ANIONS BY ION CHROMATOGRAPHY”, Part 2000 - Physical and Aggregate Properties, Part 4000 - Inorganic Nonmetallic Constituents, Part 5000 - Aggregate Organic Constituents, 4110 DETERMINATION OF ANIONS BY ION CHROMATOGRAPHY. Among them, the ion chromatography (IC) is the only reliable option for the determination of inorganic anions at trace levels [, , ]. The obtained limits of detection (LODs) are in the range of 2.1–32.6 ng/L based on the s/n = 3 and injection volume of 50 μL. The present system used cation-exchange and anion-exchange columns … Determination of trace anions in high-nitrate matrices by ion chromatography. J Chromatogr A. 1. Monolithic anion-exchange column is used for preconcentration of trace anions. DETERMINATION OF SELECTED ANIONS IN WATER BY ION CHROMATOGRAPHY . Determination of the common anions such as bromide, chloride, fluoride, nitrate, nitrite, phosphate, and sulfate often is desirable to characterize a water and to assess the need for specific treatment.

Thus, data on the ionic composition of a sample can be obtained either by two parallel analyses on two different ion chromatographs, or by two consecutive analyses of the same sample with one instrument but with different columns and under different eluent conditions.

In addition, the need to measure the concentration of the disinfection by-products chlorite, chlorate, and bromate has arisen. the concept of IC was later successively widened and IC can applied in different area. If the address matches an existing account you will receive an email with instructions to reset your password. Ion chromatography is one of the most popular methods in the determination of anions in various sample matrixes. An ion chromatography (IC) method has been proposed for the determination of seven common inorganic anions (F(-), H(2)PO(4)(-), NO(2)(-), Cl(-), Br(-), NO(3)(-), and SO(4)(2-)) and/or five common inorganic cations (Na(+), NH(4)(+), K(+), Mg(2+), and Ca(2+)) using a single pump, a single eluent and a single detector. Introduction Determination of the common anions such as bromide, chloride, fluoride, nitrate, nitrite, phosphate, and sulfate often is desirable to characterize a water and to assess the need for specific treatment. Method 4110 D is applicable to untreated and finished drinking water as well as drinking water at various stages of treatment. 2 PRINCIPLE The sample is passed through a column © 2018 American Public Health Association, American Water Works Association, Water Environment Federation, Table of Contents   |   Privacy Policy   |   Terms of Use  |   Contact Us   |   Site Credits.
