可以見所得到了，檢索號好像要檢索機構(gòu)出具的。 這是全部檢索內(nèi)容 IL-USA-DLLME Method to Simultaneously Extract and Determine Four Phenylurea Herbicides in Water Samples 作者: Wang, SL (Wang, Suli)1,2; Liu, CY (Liu, Congyun)1; Liu, FM (Liu, Fengmao)1; Ren, LP (Ren, Liping)1 來源出版物: CURRENT ANALYTICAL CHEMISTRY 卷: 7 期: 4 頁: 357-364 出版年: OCT 2011 被引頻次: 0 (來自 Web of Science) 引用的參考文獻: 34 [ 查看 Related Records ] 引證關(guān)系圖 摘要: An ionic-liquid ultrasound-assisted dispersive liquid-liquid microextraction method (IL-USA-DLLME) was introduced to determine four phenylurea herbicides (i.e., isoproturon, monolinuron, linuron, and diuron) in water samples with high performance liquid chromatography (HPLC). The ionic liquid of 1-hexyl-3-methylimidazolium hexafluorophosphate [HMIMPF6] was dispersed into the aqueous sample solution in fine droplets by ultrasound and was used as the extraction solvent; the phenylurea herbicides were concentrated into the ionic liquid phase. The extraction conditions, such as the volume of the extraction solvent, sonication and centrifugation time, ionic strength, and the emulsification-extraction temperature, were optimized. Under the optimized conditions, the linear correlation coefficient ranged from 0.9954 to 0.9969 for concentration levels of 2-100 mu gL(-1). The good recovery (68-100%) of target analytes was obtained from the water samples. The relative standard deviations (RSDs, n=6) ranged from 2.3-9.5%, and the limits of detection (LODs) for the herbicides were between 0.10 mu gL(-1) and 0.24 mu gL(-1). The applicability of the proposed method was evaluated by the extraction and determination of phenylurea herbicides from several natural water samples. 入藏號: WOS:000300354500011 文獻類型: Article 語種: English 作者關(guān)鍵詞: IL-USA-DLLME; Phenylurea herbicides; Water samples; HPLC KeyWords Plus: LIQUID-LIQUID MICROEXTRACTION; ULTRASOUND-ASSISTED EMULSIFICATION; ATOMIC-ABSORPTION-SPECTROMETRY; POLYCYCLIC AROMATIC-HYDROCARBONS; CHROMATOGRAPHY-MASS SPECTROMETRY; SOLID-PHASE MICROEXTRACTION; GAS-CHROMATOGRAPHY; ORGANOPHOSPHORUS PESTICIDES; FLAME RETARDANTS; SENSITIVE METHOD 通訊作者地址: Liu, FM (通訊作者),China Agr Univ, Beijing 100193, Peoples R China 地址: 1.
