| Abstract: | At pH = 6. 5, trace zinc in alcoholic drink from mare's milk was adsorbed and collected by mercaptowool, then eluted with diluted solution of hydrochloric acid (pH = 3. 5 ), separated from disturbing ions, and determined by using spectrophotometric method and coloring with the zinc reagent. The error for this method is 2. 6 percent. The result is satisfied. |
