Abstract

In the current study the conditions for cloud point extraction preconcentration of Ge(IV) in the form of a complex with 6,7-dihydroxy-2,4-diphenylbenzopyrylium bromide in the micellar phase of the nonionic surfactant triton X-100 were studied and optimized. It is shown that the introduction of ammonium benzoate into the studied system with a Triton X-100 nonionic surfactant concentration of 0.5 vol.% and adjusting pH to 1.0 leads to the immediate initiation of the formation of a micellar phase at room temperature. The method of graphite furnace atomic absorption determination of Ge(IV) after its cloud point extraction preconcentration as complex with 6,7-dihydroxy-2,4-diphenylbenzopyrylium bromide has been developed. The calibration graph is linear in the concentration range of 0.05-5.5 mg/dm3, and the limits of detection and quantification are 0.015 and 0.05 mg/dm3, respectively. The proposed method has been successfully applied to the analysis of standard reference materials of geological samples, and the relative standard deviation does not exceed 4.9%.
