Green strategies for decontamination of analytical wastes

Within the paradigm of green analytical chemistry, we discuss the different options for cleaning analytical wastes in the literature, paying special attention to on-line recycling of solvents, degradation of toxic compounds and trace-element passivation. The objective of this review is to present and to evaluate critically suitable methodologies that can be incorporated into analytical methods in order to reduce or to avoid the generation of toxic wastes, which could cumulate in the laboratory and have to be managed outside, so increasing the risks and the cost of analysis.
