Adsorption of Cu(II) from aqueous solution on sulfuric acid treated paiygorskite

摘要

The absorption behavior of Cu~(2+) from aqueous solution on sulfuric acid treated paiygorskite were investigated, the results showed that paiygorskite had high absorption ability for Cu~(2+) from aqueous solution. Effects of the shaking time, pH and the copper ion concentration on the removal rate were discussed. The absorption behavior of Cu~(2+) could be well imitated by the Langmuir isothermal equation.
