%X The anion and cation(F-,Cl-,NO2-,Br-,NO3-,SO42-,PO43-,Li+,Na+,NH4+,K+,Mg2+ and Ca2+) in leaching solution of smelting slag were determined by reagent free ion chromatography.The separation conditions of anion: cation exchange column Ion Pac AS19,gradient elution with potassium hydroxide solution,suppressed conductance detection,flow rate of 1 mL/min;separation conditions of cation: anion exchange column Ion Pac CS16,gradient elution with methanesulfonic acid solution,suppressed conductance detection,flow rate of 1.3 mL/min.The relative standard deviations(RSDs) of retention time,peak height and peak area of testing ions within one day were less than 0.35 %,1.8 % and 1.1 %,respectively.The RSDs of retention time,peak height and peak area of testing ions in continuous five days were less than 0.78 %,2.4 % and 1.6 %,respectively.The concentration of determined ions with its peak area had good linearity(r=0.999 0-0.999 9).The detection limit was lower than 20 μg/L.The anion and cation in leaching solution of imported scale slag,vanadium slag and manganese-rich slag were determined with recoveries of standard addition in the range 86%-110%.
