Abstract
The trueness of results in selenium determination in certified, biolog ical samples (bovine liver, marine materials) after high pressure ashi ng and microwave digestion by use of FI-HG-AAS-technique is improved b y optimizing Se(VI)-prereduction. Heating the sample solution to 70 de grees C for 50 min in open-topped vessels yields selenium recoveries o f nearly 100 % at all materials examined. Microwave digestion is as ef fective as high pressure ashing for selenium mineralization.
