Abstract

Research has been done about influence of the presence of metal ions Cd (II) on the adsorption of metal ions Pb (II) by using adsorbents napa land from areas Aripan, South Solok. Napa soil contains 63.20% of silica and alumina 16:55%, it was lmost  same as the content of silica and alumina in  zeolite nature so that it can be used as an adsorbent. In this research studied the influence of  presence of metal ions Cd (II) metal ions on the absorption of Pb (II) with some parameters, such as the initial concentration of the solution, the addition of metal ions Cd (II), pH and temperature of heating the adsorbent. Then also studied the regeneration of both metals by using a solution of 1% HNO3. These results indicate that the presence of metal ions Cd (II) decrease the absorption of the metal ions Pb (II). The optimum concentration of metal ion uptake of Pb (II) was 150 mg / L, the optimum concentration of the addition of metal ions Cd (II) is ½ times of concentration of metal ions Pb (II). The optimum pH for metal ions Pb (II) was 5 and 6 for the metal ions Cd (II). While the optimum  adsorbent heating temperature is 125 ° C, and the percentage of regenerating metal ions Pb (II) was 64 326% and Cd (II) was 38 675%.
