| Abstract: | A method for the determination of seven trace inorganic anions(F-,NO-2,Cl-,Br-,NO-3,PO3-4,SO2-4) on the surface of printed circuit board(PCB) was established by ion chromatography combing with microwave preconcentration.The PCB samples were extracted by water,and preconcentrated with microwave oven.The IC separation was carried out on Ionpac AS23 analytical column using 4.5 mmol/L Na2CO3-0.8 mmol/L NaHCO3 as mobile phase at constant flow rate of 1.0 mL/min.Under the optimal conditions,seven anions were succ... |
