Removal of Mercury from Aqueous Solutions by Shredded Rubber.

摘要

Shredded or ground rubber absorbs mercury from aqueous solutions. Mercury concentration was reduced from 100ppm to less than detectable levels (5ppm) by passing the solution through a column of finely divided tire rubber. Treatment of the rubber with sulfide solutions increases mercury removal capacity by 25%. Mercury cannot be eluted quantitatively,but may be recovered by destructive distillation of the rubber.
