Abstract
The separation of chloro complexes of metals has been carried out using micro columns and a strong acidic eluent. The micro column was packed with silica gel, particle size 10 μm, impregnated with methyltri- n-octylammonium chloride. Three or four chloro complexes of iron, nickel, copper, tin, antimony, mercury, lead and bismuth were separated by using –8 N hydrochloric acid with or without a small amount of perchloric acid as eluent. The analysis is ca. 20 min, and the H value is ca. 0.2 mm. Quantitative determination between 1 ng and 1 μg is possible.
