| Abstract: | Ruthenium is extracted by benzyl alcohol from 5M LiCl containing ethyl-alpha-isonitrosoacetoacetate at pH 4-6. The extraction is quantitative if the solution is heated to boiling for 15 min. The benzyl alcohol extract shows maximum absorbance at 470 nm and at this wavelength Beer's law is obeyed over the ruthenium concentration range 0.1-1.8 mug ml . The error is 4% for 0.5 mug ml . |
