Abstract

Clams are the food liked by people in Indonesia. Clams also contain much nutrition such as protein, vitamin C, calcium, iron, vitamin B12, vitamin B6, and carbohydrate. This research aims to determine the content of lead (Pb) metal in green clams and blood clams. The research was done by using the atomic absorption spectrophotometry, in which the clam samples must be wetly destructed to separate the lead (Pb) metal with the organic compound in those samples. The destruction result with concentrated HNO3 was then washed with 10% of HNO3 for two times, dried, and dissolved with aqua bides. The sample solution was then read in the wavelength of 217 nm. The absorbency sample obtained was then put inside the linier regression equity that had been made which is y = 0,0266 x + 0,0008 to determine the amount of lead (Pb) metal in the sample. The analysis results of the lead (Pb) metal amount in the samples are 0,2537 mg/kg and 0,1867 mg/kg for the green clams and blood clams respectively. The amount of lead (Pb) metal in the clams are still safe to be consumed as long as it does not exceed the threshold amount set. Based on SNI 7387-2009, the maximum amount of lead (Pb) metal amount in the clams safe to be consumed is 1,5 mg/kg. Keywords : Clams, Lead Metal (Pb), Destruction, Atomic Absorption Spectrophotometry
