Quinoline-8-ol, one of the most popular and versatile organic reagents, is known to react with several metals, because it has both a basic nitrogen and a phenolic group. Hence, quinoline-8-ol and its derivatives have been widely used as chelating and/or sorbent extraction agents in on-line flow injection analysis (FIA) along with a suitable detection technique. The state of the art for using quinoline-8-ol and its derivatives in FIA was studied in terms of the selectivity, sensitivity and precision. Emphasis was placed on validating these procedures by analyzing certified reference materials and applying these analytical methodologies to real samples for the determination of inorganics.
