Choosing appropriate dilution ratio to dilute oil field waste water, the diluent was filtered by 0.22 um microporous membrane and treated by IC-RP column.If the sample contains heavy metal and transition metal ions, it must be treated by IC-Na column . Using CIC-D120 ion chromatograph, SH-AC-3 anion column, 3.6 mM Na2CO3+4.5 mM NaHCO3 eluent and bipolar pulse conductance method,under the recommended chromatographic conditions,the chromatogram is as follows.
