Abstract

Musi river has been polluted by heavy metal. As for the metal contamination which has polluted such as the metalic lead. The purpose of this study to reduce the level of metalic lead (Pb) in salted fish by immersion using newsprint. The metal (Pb) inspection performed by qualitative and quantitative. The qualitative analysis carried out by reagent ditizon and the quantitative analysis used The Atomic Absorption of Spectrophotometry with wavelength 283,3 nm. From the analytical results obtained the level of Pb toward there samples of saltyfish gabus before the immersion of each was 0,49 mg/kg, 0,42 mg/kg, 0,66 mg/kg. However, after soak by using ink newsprint or not is obtained on the merchants sampel A,B,C. The highest level after soaking with newsprint by in in consecutively 0,46 mg/kg, 0,25 mg/kg, 0,24 mg/kg and the lowest were 0,32 mg/kg, 0,15 mg/kg, 0,18 mg/kg. The sampel data in the merchant A,B,C. The higest level after soaking by the newsprint without ink 0,32 mg/kg, 0,22 mg/kg, 0,18 mg/kg. And thelowest were 0,12 mg/kg, 0,13 mg/kg, 0,12 mg/kg. Based on this study concluded there is a decrease in the sample A,B,C. After soaking the newsprint with ink for 45 minutes constantly: 34,69%, 64,29% and72,73%. Moreover, the soaking without ink fot 45 minutes to the sampel (merchant) A,B and C continuely 75,51 %, 69,05 %, 81,82 %.
