Greening sample preparation in inorganic analysis

Sample preparation aims to convert analytes to a more suitably detectable form, to separate them from the sample matrix or to concentrate species for trace analysis. Classical procedures often yield large amounts of toxic waste, but environment-friendly alternatives can be implemented without impairing the analytical performance. Green methods are also safer, and reduce costs and risks of sample contamination. This overview focuses on application of these strategies to inorganic analysis. (C) 2013 Elsevier Ltd.
