Abstract

After being activated in the chromate solution

silver nanoparticles modified graphite electrodes can be used to make a new type of the potential sensor of chromium（Ⅵ）.The result of the experiment in which the sensor is used to determine chromium（Ⅵ）shows that the modified electrode has a sensitive potential response to chromium（Ⅵ）.It has a wide linear range of 1.0×10-7～1.0×10-2mol·L-1

and the detection limit is 4×10-8mol·L-1.The electrode is used for determining chromium（Ⅵ）in water

and the results can meet the analysis requirements.
