The parameters influencing the extraction were investigated and optimized. Under optimal conditions, a good linearity was found between the concentration and the peak area in the range from 0.2 to 40μg L-1 (r2 > 0.99), and detection limits were in the range from 0.062 to 0.21μg L-1. Real water samples were used for validating the method and recoveries of spiked samples were over the range from 82.0 to 100%. The results indicated that TiO2 nanotubes repesented an attractive alternative sorbent for the enrichment and trace analysis of such pollutants. Figure This paper established a new, simple and sensitive method for the determination of benzoylurea insecticides in water samples with solid-phase extraction using TiO2 nanotubes cartridge prior to high-performance liquid chromatography. Under optimal conditions, the detection limits were in the range of 0.062-0.212 μgL-1 for diflubenzuron, chlorbenzuron, triflumuron, flufenoxuron, and chlorfluazuron, respectively. Real water samples were used for validating the proposed method and good spiked recoveries are over the range of 82-100.2% Springer-Verlag, 2010 Benzoylurea insecticides nationallicence TiO2 nanotubes nationallicence High-performance liquid chromatography nationallicence Water samples nationallicence Huang Yunrui School of Chemistry and Environmental Sciences, Henan Key Laboratory for Environmental pollution Control, Key Laboratory for Yellow River and Huaihe River Water Environment and Pollution Control, Ministry of Education, Henan Normal University, 453007, Xinxiang, People's Republic of China aut Zhou Qingxiang School of Chemistry and Environmental Sciences, Henan Key Laboratory for Environmental pollution Control, Key Laboratory for Yellow River and Huaihe River Water Environment and Pollution Control, Ministry of Education, Henan Normal University, 453007, Xinxiang, People's Republic of China aut Xie Guohong College of Resources and Environment, Henan Institute of Science and Technology, 453003, Xinxiang, China aut Liu Haijin School of Chemistry and Environmental Sciences, Henan Key Laboratory for Environmental pollution Control, Key Laboratory for Yellow River and Huaihe River Water Environment and Pollution Control, Ministry of Education, Henan Normal University, 453007, Xinxiang, People's Republic of China aut Lin Haiying Jilin Municipal Research Institute of Environmental Sciences, 132001, Jilin, China aut Microchimica Acta Springer Vienna 172/1-2(2011-02-01), 109-115 0026-3672 172:1-2<109 2011 172 604 https://doi.org/10.1007/s00604-010-0472-4 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/s00604-010-0472-4 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Huang Yunrui School of Chemistry and Environmental Sciences, Henan Key Laboratory for Environmental pollution Control, Key Laboratory for Yellow River and Huaihe River Water Environment and Pollution Control, Ministry of Education, Henan Normal University, 453007, Xinxiang, People's Republic of China aut NATIONALLICENCE 700 1- Zhou Qingxiang School of Chemistry and Environmental Sciences, Henan Key Laboratory for Environmental pollution Control, Key Laboratory for Yellow River and Huaihe River Water Environment and Pollution Control, Ministry of Education, Henan Normal University, 453007, Xinxiang, People's Republic of China aut NATIONALLICENCE 700 1- Xie Guohong College of Resources and Environment, Henan Institute of Science and Technology, 453003, Xinxiang, China aut NATIONALLICENCE 700 1- Liu Haijin School of Chemistry and Environmental Sciences, Henan Key Laboratory for Environmental pollution Control, Key Laboratory for Yellow River and Huaihe River Water Environment and Pollution Control, Ministry of Education, Henan Normal University, 453007, Xinxiang, People's Republic of China aut NATIONALLICENCE 700 1- Lin Haiying Jilin Municipal Research Institute of Environmental Sciences, 132001, Jilin, China aut NATIONALLICENCE 773 0- Microchimica Acta Springer Vienna 172/1-2(2011-02-01), 109-115 0026-3672 172:1-2<109 2011 172 604 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
