Indicative Project

Analysis of Sulphur-containing inorganics anions by 2D-IC

Background Info

Sulphur-containing inorganic anions e.g sulphite (SO32-), sulphate (SO42-), thiocyanate (SCN-), thiosulfate (S2O32-) are commonly encountered in soil sediments, hot springs, and lake waters. They are also frequently used in many industrial applications. Their speciation and quantitation are very important to the understanding of those processes.

Project Description

Many sulphur-containing species, due to their redox chemistry, can readily react with each other, decompose over time, or be oxidized in the presence of air. They are also very sensitive to the pH of the solution, which would affect the distribution of the species with time. All these factors make the determination of the sulphur-containing anions a very exciting task.

The project would aim to develop a method to separate and quantify sulphur-containing anions by supressed ion chromatography; test the reliability, repeatability and sensitivity of the method to ensure the development of an analytically sound product for soil and water matrices; and submit the method for NATA accreditation.
