Cation Exchange Capacity (CEC)

Sand Clay No charge. Negative charge. Does not retain Attracts and retains ions. ions. Figure 1: Substitution of silica by aluminum in soil clay particles causes clays to have a negative charge. Because of this negative charge, the soil can hold on to positively charged ions such as calcium (Ca 2+), magnesium (Mg )

Column Chromatography Procedures

Once the sample is in the column, fresh eluting solvent is added to the top and you are ready to begin the elution process. For the dry method, first dissolve the sample to be analyzed in the minimum amount of solvent and add about 100 mg of silica gel. Swirl the mixture until the solvent evaporates and only a dry powder remains.
