ANALYSIS OF METAL CONTENTS LEAD AND CADMIUM IN URETIC ACID JAMU BY USING ATOMIC ABSORPTION SPECTROPHOTOMETRIC

Abstract

Analysis of metal contents lead and cadmium in jamu asam urat using atomic absorption spectrophotometric has been done. The aim of this study is to analyze metal contents (lead and cadmium) in jamu asam urat with diffrent brands which are circulate in Padang cyti. Three samples of jamu asam urat with diffrent brands were analyzed the metal contents of lead and cadmium using atomic absorption spectrophotometric. The level of lead metal was obtained using regression equation y = 0.05378 + 0.02963x with R = 0.9977, and the level of cadmium metal was obtained using regression equation y = 0.08236 + 0.23186x with R = 0.9945. The result of this study showed that three samples were not detected containing metal cadmium, but three samples were positive containing metal lead, 2.2055 ppm (samples I), 3.6465 ppm (samples II), and 3.0156 ppm (samples III). The renits showed that all samples qualified for healy metal contamination by BPOM that less than 10 ppm for Pb and less than 0.3 ppm for Cd heavy
