Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
A sensitive analytical method for triclosan (TCS) in water samples, which involves enrichment with bamboo-activated charcoal (BAC) and detection with HPLC-ESI-MS is developed. The effects of some important operation parameters, such as the eluant and its volume, flow rate, the volume and the acidity of the sample and the amount of bamboo-activated charcoal, on the recovery of TCS were investigated and optimized. Under the optimum conditions, the spiked recoveries of TCS in real water samples were achieved in the range of 108.5%-113.4%. The linearity of the method was observed in the range of 0.02-20 μg L-1, with correlation coefficients (r2) >; 0.9990. The limit of detection ( LOD ) was 0.002 μg L-1 based on the ratio of chromatographic signal to base line noise(S/N = 3). The concentrations of TCS in the real environmental water samples collected in Darning Lake, Xiaoqing River and Yellow River at Jinan, Shandong Province were also determined using this method.
