| Abstract: | Sample was dessolved in nitric acid.And disturbance was eliminated with the addition of diammonium hydrogen phosphate and magnesium nitrate as inhibitor. The lead was determined by Graphite furnace atomic absorption spectrum. Working curve in range of 0.05-0.50 ug/mL of lead solution was prepared.Recovery was found in range of 95%-106% and relative standard deviation in 3.01%-5.82%.Preeition and accuracy of determination are proved to be fine. |
