2. There are five interferences commonly encountered in spectrophotometric techniques. (a) Explain, with the aid of examples and/or diagrams, the consequence of matrix interference in Atomic Absorption Spectrometry (AAS). [3] (b) Explain the origin of ionisation interference in Atomic Absorption Spectrometry (AAS) and explain how it may be counteracted. [5] (c) Spectral and background interference can be the most problematical interferences encountered in Inductively Coupled Plasma - Atomic Emission Spectrometry (ICP-AES). With the aid of diagrams, explain how these interferences arise and explain how they may be counteracted. [15] (d) Name and briefly explain why one of the 5 common spectrophotometric interferences is not problematical in Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). [2]

An analyst is required to perform arsenic analysis by atomic spectroscopy. The arsenic test sample is contaminated with calcium salts. (i) With the aid of relevant chemical equations and diagrams, describe how calcium contaminants create spectral and chemical interferences in atomic analysis and give examples of methods used to overcome these interferences. (ii) With the aid of relevant chemical equations and diagrams, describe a suitable sampling method for arsenic analysis that will maximise analytical sensitivity.
