Water analysis by ICP-AES
Water is a valuable commodity even where it is abundant, and its quality in respect of dissolved or suspended material is of great importance in many areas. The need for care with water destined for human consumption is obvious, in an age where the contamination of water supplies by human activity is all too common. The composition of water used in food production (e.g. in irrigation and pisciculture) is likewise very important. The effect of industrial pollution on the aqueous environment needs regular monitoring, and this in turn implies a knowledge of the composition of the water, and the mode of entry and ultimate fate of any contaminants. In addition, many industrial processes require the use of water of guaranteed quality, and in most countries, industries are subject to legislative control on the quality of water they discharge into national water systems and sewers. This widespread interest in the composition of water requires a commensurate investment in facilities for its analysis, and the ICP is playing an increasing part in this effort.
