摘要：The potentiometric method of cell type concentration is used to analyze the copper metal in leachate. This method is relatively good because it has a correlation coefficient of 0.9997 and linear region in the concentration range 1x10-5 - 1x10-3 mol L-1. The precision of this potentiometric method is low because the persent of RSD produced is 0.6% with an average accuracy 0f 95.35%. The detection limit (LoD) of the measurable method is 1.085x10-6 mol L-1 with LoQ 1.313x10-6 mol L-1. While the LoD instrument 1.217x10-6 mol L-1 and LoQ 1.560x10-6 mol L-1. In addition, this method is very selective with the selectivity coefficient of -3.7 and it has uncertainty of measurement 9.7x10-7 ± 1.282x10-6 to 9.12x10-5 ± 3.5x10-5 . Potentiometric method of cell type of concentration hasanoptimumconditionatpH5andtemperature30˚C.Theconditionsof copper in leachate water renged from 9.253x10-5 to 8.696x10-4 mol L-1.
