方案摘要:
方案详情:
2016年5月31日,《土壤污染防治行动计划》(简称“土十条”)正式由国务院印发实施,此后一年多的时间里环境土壤普查已覆盖全国,多项环境土壤标准发布。
传统手动方法耗时耗力,很难满足大量样品的检测需求,为了提高效率,现参考标准(HJ 835-2017土壤和沉积物 有机氯农药的测定 气相色谱-质谱法)来摸索全自动前处理的可行性。
本实验使用了莱伯泰科压力溶剂萃取系统(HPSE)提取土壤中的23种有机氯,SePRO全自动高通量柱膜通用固相萃取系统净化,MV5多通道平行浓缩系统浓缩后用气质联用仪进行检测,创建了土壤中有机氯检测的一整套方法。

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
