title: The removal by crab shell of mixed heavy metal ions in aqueous solution.
abstract: In order to examine the inhibition effect of other heavy metal ions on the removal by crab shell of heavy metal ions in aqueous solutions, three ions (Pb(2+), Cd(2+), Cr(3+)) were used in single, binary and ternary systems. In single heavy metal ion systems, the removals of Cr(3+) and Pb(2+) were much higher than that of Cd(2+). In binary heavy metal ions systems, Cd(2+) did not affect Pb(2+) removal while Cr(3+) had a severe inhibition effect on the removal of Pb(2+). Cd(2+) removal was slightly affected by the presence of Pb(2+); however, it was severely affected by the presence of Cr(3+). The inhibitory effect of Cd(2+) on Cr(3+) was relatively lower than that of Pb(2+).
