Abstract

  An interaction of chromium(VI) with basic dye of triphenylmethane row fuxine has been studied. Formed ion associate once-through extracted by the dichloroethane from pH 1.0 to 0.5 M hydrochloric acid solutions. The ion associate is submitted to the main law of spectrophotometry in the 0.012 – 5.0 mcg/mL range of chromium contents,  ε537 = 5 · 104 ± 500  (L · mol-1 · cm-1). The molar ratio between chromium(VI) anion and fuxine cation in formed compound has been determined, which is 1 : 1. The determination of chromium is hindered by iron and antimony. The suggested method was applied in microgram amounts of chromium(VI) ion determination in waste waters of galvanic manufacture in soils and haricot.
