ADSORPTION EFFICIENCIES OF CALCIUM (II) ION AND IRON (II) ION ON ACTIVATED CARBON OBTAINED FROM PERICARP OF RUBBER FRUIT

Inline - Skates - Youth Determination of adsorption efficiencies of activated carbon from pericarp of rubber fruit for calcium (II) ion and iron (II) ion has been performed by flowing the solutions of these ions through a column of activated carbon.The weights of activated carbon in 500 mL buret column (diameter 3.2 cm) for flowing calcium (II) ion
