The difference in toxicity is one of the main reasons for the recent development of analytical procedures for differentiating chromium (Cr) species. Non-chromatographic speciation procedures using sorption-based systems offer very convenient tools and can be used as fast, cheap alternatives to chromatography. The methods based on sorbent extraction have proved to be the most attractive, due to their high separation and preconcentration efficiency.This review presents procedures based on sorption principles for use in Cr-speciation analysis. They are discussed and compared in terms of selectivity and efficiency. This review covers the state of the art since 2005.
► Chromium speciation analysis using sorption principles are discussed. ► Separation of Cr species could be achieved simultaneously with their enrichment. ► These procedures are most advantageously using flow systems.
