Trace analysis of anions in organic matrices by ion chromatography coupled with a novel reversed-phase column for on-line sample pretreatment
摘要:
An ion chromatography (IC) system coupled with on-line column-switching technique was used to determine anions of μg/g levels in organic chemicals of analytical reagent grade. A novel polystyrene-divinylbenzene-carbon nanotube (PS-DVB-CNT) stationary phase was utilized for matrix elimination. A calibration study was conducted by preparing and analyzing eight concentrations (between 10 and 5000 μg/L) of eight standards in deionized water. The linearity was between 0.9978 and 1. And the detection limits ranged from 1.54 μg/L to 10.02 μg/L. A spiking study was performed on two representative organic chemicals. The recoveries were between 84.3% and 119.6%.
