Abstract

This research was aim to identify the effectiveness of rice husk charcoal as a bioadsorbent in absorbing heavy metals Pb in freshwater snail meat (Pomacea sp). The main material used was adult fresh water snail with body weight of 80-120 g/head obtained from the swamp waters of Banjar Regency, South Kalimantan. Bioadsorbent was used as much as 10% and 15% with a duration of contact on freshwater snail meat 6, 12, 24, 48 and 72 hours. Analysis of Pb métal content using Atomic Adsorption Spectrofotometry (AAS) instrument. The results showed that: (1) the use of rice husk charcoal as a bioadsorbent was able to reduce the levels of Lead (Pb) in freshwater snail meat (2) duration of contact of 24 hours with the use of rice husk charcoal as much as 10% and 15% was could reduce lead (Pb) in freshwater snail meat from 20,444 mg/kg to < 0.001 mg/kg with 99.99% absorption effectiveness. The used of rice husk charcoal on freshwater snail meat increased the pH of freshwater snail meat from 5.5 to 7.8 at 10% used and 8.03 at 15% used, respectively.
