摘要

摘要:研究了一种新型的松树皮固相萃取生物吸附剂。利用傅里叶变换红外光谱(FTIR)和扫描电镜(SEM)对松皮的形貌和成分进行了表征。利用该生物吸附剂制备废水，采用高效液相色谱-紫外检测(HPLC-UV)法测定苯丁酮、磺胺乙嗪、多菌灵和利努龙的含量。以洗脱溶剂、进样量、萃取ph为条件对固相萃取条件进行了优化。结果表明，所制备的吸附剂具有良好的重复性。相对标准偏差(n = 3)在0.3 ~ 2.2%之间。检出限(LOD)在0.11 ~ 0.4µg.L−1之间。该方法用于某污水处理厂出水中分析物的测定。

Determination of phenylbutazone, sulfamethazine, carbendazim and linuron using a novel pine bark biosorbent for solid-phase extraction (SPE) with high-performance liquid chromatography (HPLC)

Abstract The paper presents a novel pine bark based biosorbent for solid-phase extraction (SPE). The morphology and composition of the pine bark were characterized using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The biosorbent was used for the preparation of wastewater for the determination of phenylbutazone, sulfamethazine, carbendazim, and linuron by high performance liquid chromatography with ultraviolet detection (HPLC-UV). The SPE conditions were optimized with respect to elution solvent, sample volume, and extraction pH. The results showed that developed sorbent provides good repeatability. The relative standard deviation (n = 3), was between 0.3 and 2.2%. The limits of detection (LOD) were between 0.11 and 0.4 µg.L−1. The developed method was used for determination of the analytes in effluent from a wastewater treatment plant.

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
