Abstract

The quantitative trace analysis of ions could be deteriorated by filter papers because of the effect of adsorption. Generally the adsorption of anions on filter paper did not occurred. Instead, $Cl^-$ and $NO{_3}^-$ ions were extracted from the filter papers. However, most metal ions were adsorbed on the filter papers by the formation of hydroxide in neutral solution. The adsorption of metal ions except $Ag^+$ ion could be avoided depend on the acid concentrations.
