方案详情:
拟除虫菊酯是一类能防治多种害虫的广谱杀虫剂,对昆虫具有强烈的触杀作用,因其高效低毒,在茶叶、蔬菜、水果种植中使用广泛。茶叶中拟除虫菊酯类农药残留的检测现多用气相色谱法、气质联用法和高效液相色谱法。传统的样品前处理消耗有机溶剂多,操作繁琐,干扰较多。我们应用QuEChERS分散固相萃取前处理技术,采用气相色谱-电子捕获检测器对茶叶中8种拟除虫菊酯类农药进行分析,结果满足检测要求。

文献名: Structural, morphological and optical properties of Bi NPs obtained by laser ablation and their selective detection of L-cysteine 作者: Ramon Gabriel Teixeira Rosaa, Celso de Araujo Duartea , Wido Herwig Schreinera, Ney Pereira Mattoso Filhoa, Arandi Ginane Bezerra Jr.b, Andersson Barisonc, Fernanda Maria Marins Ocamposc a Departamento de Física, Universidade Federal do Paraná Centro Politécnico, CP 19044, 81531-990 Curitiba (PR), Brazil b Departamento Acadêmico de Física, Universidade Tecnológica Federal do Paraná, 80230-901 Curitiba (PR), Brazil c Departamento de Química, Universidade Federal do Paraná Centro Politécnico, CP 19081, 81531-990 Curitiba (PR), Brazil 摘要:In the present work we show the results of the investigation of the properties of bismuth nanoparticles (NPs) obtained by the laser ablation in water. The samples were characterized by various techniques: UV/vis spectroscopy, dynamic light scattering, transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, nuclear magnetic resonance and zeta potential. The NPs were metallic and surface oxidated, exhibiting absorption peak at 257 nm due to the surface plasmon resonance. The interaction between the NPs and various amino acids was studied and revealed a selective sensibility to cysteine on a range of concentration from 80 to 720 μM, which we attribute to a dimerization of cysteine to cystine probably complexed to the nanoparticle surface by electrostatic interactions, leading to the modification of the NP absorption spectrum. 关键词:Bismuth; Nanoparticles; Laser ablation; Cysteine

城市污水中TOC与COD的关系
TOC与COD的测定方法不同。测定COD是采用强氧化剂和加热回流的方法,只能将水中的有机物部分氧化(氧化率较低),并且测定时间较长,即使目前一些快速的

4D-脂质组学高通量工作流程
Lipid profiling from complex lipid extracts can be a challenging and time consuming task. The high complexity of samples and co-elution of isobaric or isomeric compounds complicate the confident annotation of lipids. The presented 4D-Lipidomics workflow simplifies and streamlines the annotation and validation process using mobility-enhanced MS data.

基于紫外分光光度法的水中油测试方法
矿物油组成中的共轭体系物质在紫外光区有较强的吸收,依据朗博 - 比尔定律,在256nm紫外光波长,可测定油样的吸光度来确定相应油的量。 由于紫外光度法对于油种的敏感性较强,本方法的油样需采用标准物质。
