The purpose of this research was to develop a test kit for determination the total amount of Pb(II) in water by means of colorimetry technique based on the reaction between Pb(II) and rhodizonic acid resulting in purple complex. As the purple complex could be observed only in high Pb(II) concentrated and since World Health Organization limited Pb(II) concentration in water to be no greater than 0.05 ppm. The determination total amount of Pb(II) in water was performed by analyzing the rhodizonic acid remaining from Pb(II) reaction. UV-visible spectrophotometer and Atomic Absorption Spectroscopy techniques were applied to accurate results. This test kit could examine Pb(II) concentration in water in a range of 0.01 to 0.5 ppm.
