摘要：

We report facile, template-free, surfactant-less flower and Christmas tree-like cerium hexacyanoferrate (CeHCF) modified electrodes for simultaneous measurement of environmentally hazardous metals. The hierarchical growth of CeHCF on electrode surface was controlled by electrodeposition time at constant potential. This CeHCF modified electrode exhibits a prominent electrocatalytic activity towards detection of heavy metal ions such as cadmium (Cd), copper (Cu), lead (Pb) and mercury (Hg). The peaks are separated well at CeHCF modified electrode. Well separated peaks for the detection of these heavy metals in lake and tap water samples indicating CeHCF modified electrode as successful electrode for the reported sensor.
