| Abstract: | Trace perchlorate in drinking water was determined using ion chromatography. 30 mmol/L NaOH eluent, 1 mL/min flow rate and 1 000 μL sample injection volume were used, perchlorate can be determined within 25 min. The water sample was concentrated in 10 - flod by heating. The result showed that the recoverie of perchlorate was 87.9%, detection limit was 0. 10 μg/L. The developed method is applicable for the quantitation of perchlorate in real water samples. |
