title: Extraction and spectrophotometric determination of copper with thiobenzoylacetone (3-mercapto-1-phenylbut-2-en-1-one).
abstract: The copper(II)-thiobenzoylacetone complex, extracted into benzene, is used for photometric determination of copper at 410 nm after excess of reagent has been removed by scrubbing with a buffer at pH12. The extraction is quantitative over a broad pH range (3.5-9.5). The method is highly sensitive for the determination of copper.
