Research about ability activated carbon had been done for the adsorption of copper metal ion. Parameter which investigated were variation of particle size 60, 80, 100 and 140 mesh, variation of contact time 15, 30, 60, 90 and 120 minutes, variation of concentration 50, 60, 70, 80, 90 and 100 ppm, variation of pH 4, 7 and 9. Measurement of concentration copper metal ion in condensation by Atomic…
