Abstract

The use of the calibration and of the standard addition methods in determining dissolved lead in Borobudur's control tanks water were compared. The aim of the study was to develop the standard addition method to determine very low concentrations of dissolved lead using Flame Absorbtion Spectrophotometry (F-AAS). Sampling was executed from five points: a point at the south side, a point at the south west, and three points at the north of the Borobudur Temple. The linearities of both curves were compared. The linearity of the calibration curve was found to be 0.957092, while of the standard addition had a linearity of ≥ 0. 995 (except sample AS). Both methods gave different dissolved lead concentrations. The result of the calibration method was higher than that of the standard addition method.
