| dc.description.abstract | Copper metal is a heavy metal from industrial waste and relatively often found as contaminants in the water, because it was the presence of copper metal waste should be minimized. One method that has been developed to minimize the presence of Cu2+ is the metal adsorption process, is one of the natural zeolite adsorbents are widely used for the adsorption process because it is widely available in nature and has a high selectivity. This study aims to determine a suitable kinetic model for metal adsorption process of Cu2+ to see the power adsorption activated natural zeolite and the influence of temperature on the adsorption rate constant. The study was conducted by varying the contact time (0, 15, 30, 45, 60, 75 and 90 minutes) and temperature (300C, 400C and 500C). Copper metal adsorption results were analyzed using atomic absorption spectrophotometer (AAS). The result showed that the model is suitable for metal adsorption kinetics of Cu2+ with activated natural zeolite following the model of first order with a value of k = 0.0119 min-1 for the variation of the contact time and each k = 0,0111 min-1; 0,0123 min-1; 0,0145 min-1 for a temperature variation of 300C, 400C and 500C and the value of the activation energy for the adsorption process is equal to 10,841 kJ/mol. | en_US |
