Abstract:
Objective To establish a method for determination of copper, manganese and cadmium in human urine by transversely heated GFAAS.Methods Matrix modifiers were used and background absorption was deducted, copper, manganese and cadmium in human urine were determined by transversely heated GFAAS after digestion.Results 5 g/L Mg(NO3)2 was taken as the matrix modifier when copper and manganese were determined and 0.3 g/L Mg(NO3)2 and 5 g/L NH4H2PO4 was taken as the matrix modifier when cadmium was determined.Under the designed standard conditions, the detection limits of copper, manganese and cadmium were 0.028-0.060 ?g/L;RSDs were 1.1%-5.1%;Recovery rates were 94.2%-107.5%.Conclusion The method is simple, accurate and sensitive, and is applicable to the determination of copper, manganese and cadmium in human urine.
