Abstract
Dried green mussel [Perna viridis, (Linneaus, 1758)] was soaked in acetic acid solution at a concentration of 10%, 15%, 20%, and 25% for 0min, 30min, 60min, and 90min. The content of heavy metals such as Pb, Cr, and Cd after soaking were analyzed by Atomic Absorption Spectrometer (AAS). The results indicated that after soaking in acetic acid solution at a concentration of 25% for 90min reducing heavy metal Pb from 2.879μg · g–1 to 1.407μg · g–1, Cr from 0.730μg · g–1 to 0.362μg · g–1, and Cd from 0.710μg · g–1 to 0.441μg · g–1. The increasing concentration of acetic acid solution and the longer soaking time, the levels of heavy metals (Pb, Cr, Cd) in green mussel will decreasing. Interestingly, acetic acid was able to chelate the studied heavy metals in green mussel.
