内容説明
One of the problems in the analysis of natural and potable waters is that the equipment used is often insufficiently sensitive to detect low concentrations of organic and inorganic substances present in the samples. This unsatisfactory situation is compounded by the increasingly strict directives on pollution control and the consequent need for more sensitive detection techniques. The problem can, however, be overcome to some extent by preconcentrating the samples before analysis, effectively reducing the detection limit of the analytical method, and thus enabling background levels of substances in the environment to be measured. These volumes review the techniques available for preconcentration, and explain how each method can be applied to cations, anions, organic substances and organometallic compounds. Methods involving complex formation and direct preconcentration are covered in volumes 1 and 2 respectively. The volumes are also available individually (Vol 1 ISBN = 0-19-855395-1 and Vol 2 ISBN = 0-19-855394-3)
