Quinalizarin complexone

Sulphonated Alizarin Complexone [32-35], and the related reagent Quinalizarin Complexone [36] have also been suggested for determining fluoride. The use of Quinalizarin Complexone increases the sensitivity by about 50%. Traces of fluoride have been pre-concentrated on anion exchange resin impregnated with Alizarin Complexone [37].

Several anthraquinone derivatives have been suggested for the spectrophotometric determination of germanium, namely quinalizarin (extraction of the complex with chloroform in the presence of diphenylguanidine), Purpurin (1,2,4-trihydroxyanthraquinone) [52], and Alizarin Complexone [53]. 

Other organic reagents recommended for determination of Mo include Alizarin Complexone [103], l-nitroso-2-naphthol [104], morin [105], rutin [106], quercetin [107], 1,5-diphenylcarbazone [108], quinalizarin in the presence of surfactant [109], tiron [12,31,39], and 2,2 -biquinoxalyl [110]. The FIA technique has been applied in the determination of Mo with the use of carminic acid [111].
