Perendaman Daging Kerang Hijau (Perna viridis) Menggunakan Asam Asetat dan Bubuk Sargassum sp. sebagai Penurun Kadar Logam Timbal (Pb)
Akumulasi logam berat berlebih pada kerang hijau (Perna viridis) dapat membahayakan konsumen. Sargassum sp. merupakan rumput laut yang berpotensi sebagai penurun kadar logam karena mengandung alginat yang memiliki gugus fungsi penyerap logam. Gugus fungsi seperti hidroksil dan karboksil dapat menjerap ion logam timbal (Pb) yang terdapat pada daging kerang hijau. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan bubuk rumput laut Sargassum sp. dan asam asetat sebagai penurun kadar logam timbal pada daging kerang hijau serta mengidentifikasi gugus fungsi yang terkandung dalam bubuk Sargassum sp.

期刊介绍:
The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
