Abstract
This research analyzes the use of in nature shrimp shells for biosorption of metallic ions in surface runoff. Tests were carried out with different amounts of shrimp shells (5 g and 10 g) for 200 mL of runoff, with shaking of 100 rpm for 24 h. The results evidenced the high presence of metal ions in the shrimp shells and that it directly influenced the results of the tests with the different amounts of biosorbent. The shrimp shells in nature had high concentrations of metal ions (Pb, Ni and Cu), which have high toxicity to the environment, however there had been specific metal ions (Fe, Mn, Zn and Cr) removing. According to the results, a pretreatment is required for biosorbents prior to full scale use.
