英文摘要：

A new method for the determination of copper, nickel, iron, lead, cadmium and mercury in potassium aurous cyanide was studied. The samples were digested with microwave digestion. The copper, nickel, iron, lead, cadmium and mercury ions were pre-column derived by Tera- （4-dimethylaminophenyl） -porphine （ T4 - DMAPP） to form stable chelates. These chelates were separated on a ZORBAX Stable Bound （4.6mm×50mm, 1.8μm） by gradient elution with methanol and THF as mobile phase at a flow rate of 2.0ml/min and detected with photodiode array detector from 350 - 600nm. The detection limits of nickel, copper, iron, lead, cadmium, and mercury are 40ng/L, 30rig/L, 50ng/L, 40ng/L, 20ng/L and 40ng/L respectively. The results show that most of the relative standard deviations of these ions were 1.8% - 3.4%. The standard recoveries were in the range of 92% - 106%. This method was applied to the determination of nickel, copper, iron, lead, cadmium, and mercury in potassium aurous cyanide with good results.
