In recent years, due to population growth and the rapid development of science and technology, industrial, agricultural and domestic sewage emissions is increasing, resulting in the deterioration of water quality exacerbate. Many pollutants in water pollution, toxic and hazardous organic pollutants monitoring is the focus of environmental monitoring, the environment priority pollutants blacklist of 68 kinds of organic matter accounted for 58, including phthalate esters (phthalates) and polycyclic aromatic hydrocarbons and other compounds. In the analysis of environmental samples, generally require the detected object are micro-or trace substances and therefore must be concentrated enrichment after a certain pre-processing to the detection of the instrument. The solid-phase extraction recent years developed sample pretreatment method. It has a high recovery rate, time-saving advantages of high enrichment factor, low solvent consumption and ease of operation and automation, widely used in the separation and enrichment of trace organic compounds. In this paper, the solid-phase extraction as a means of sample pretreatment, HPLC separation monitoring, phthalate esters in environmental water samples and the analysis of polycyclic aromatic compounds, the main contents are summarized as follows: (1) solid-phase extraction and high performance liquid chromatography in environmental water samples of three phthalates (o-phthalate, di-n-octyl dimethyl phthalate, dibutyl phthalate (2 - ethylhexyl) ester) were analyzed. Determined by high performance liquid chromatography conditions, including gradient elution conditions, measurement wavelength, etc.; investigated by solid phase extraction column, elution solvent, elution volume, loading rate, and the elution rate of extraction efficiency. Under optimal conditions, determine the linear range of the method detection limit, relative standard deviation, the method has been successfully applied to unsolicited and waterworks into the water sample analysis. (2) new porous materials - bamboo charcoal as solid-phase extraction materials to the whole column as high-performance liquid chromatographic separation column, the establishment of a quick analysis of 16 PAHs in environmental water samples analysis methods. Determine the gradient elution conditions measured wavelength high performance liquid chromatography conditions; examine charcoal as a solid phase extraction column extraction conditions, including the type of eluent, eluent consumption, on the sample rate, sample volume, elution rates; Under optimal conditions, determine the linear range of the method detection limit, relative standard deviation, the method has been successfully applied to the analysis of river water samples.
