| Abstract: | A comparative study between the methods of sample-digestion in the AAS determination of lead in foodstuffs by dry-ashing method and by microwave-heating in open vessel was made. It were shown by the experimental results that the treatment by micro wave heating was quicker and easier to operate, and that no significant differences of precisions and recoveries were found between these two methods. |
