Multicriteria decision analysis (MCDA) is a group of methods that aid making decisions, based on complex criteria. “Greenness” assessment of analytical procedures and analytical reagents is very complex task. Different MCDA techniques have been applied for ranking of analytical procedures according to their “greenness”, but also other criteria, like analytical performance and economic costs. These tools were used for ranking of analytical procedures for aldrin determination in water, ibuprofen determination in wastewater, imidacloprid in fruits and chloropropanols in edible oils. All assessments show that procedures based on microextraction techniques are ranked higher according to “greenness” and analytical performance criteria. Another aspect is ranking of solvents that can be used in analytical chemistry laboratories according to their environmental impact. Ecotoxicological, environmental persistence, safety parameters and potential for appropriate disposal were the assessment input criteria. Ranking allowed to assess solvents, with unquestioned, the greenest solvent – water. MCDA based solvent assessment was combined with extraction efficiencies results to select appropriate pairs of solvents for dispersive liquid-liquid microextraction for chlorophenols determination.

This research was financed by Ministry of Science and Higher Education under „Iuventus Plus” program in years 2015 – 2017, project number IP2014 048173.
