关键词： 课程思政   分析化学   考试方法改革  

摘要： 在新的高等教育形势下,《分析化学》作为化学师范专业的一门必修课程,承载着专业知识传授及思想政治教育的双重功能。为实现专业培养与立德树人协同并行的育人目标,教师除通过课堂主渠道充分发挥课程德育功能外,在《分析化学》课程结课考试中,突破传统的试题模式,探索考试内容改革,融入课程思政理念,多角度多维度创新,体现价值引领,做到“全方位育人、全程育人和全员育人”。

关键词： 物理化学   热力学   平衡态   稳定条件   化学平衡  

摘要： 化学平衡的移动规律是物理化学中重要的知识点之一。平衡稳定条件在经典热力学中占有重要的地位,但很少用于处理化学平衡问题。根据热力学原理,推导了简单的均匀隔离系统的平衡稳定条件,并将其用于分析温度和总压力对化学平衡移动的影响,结论为改变温度和总压力,使化学平衡朝着稳定平衡的方向移动。这种分析方法非常简单,也加深了我们对稳定平衡的理解。同时,也指出了该方法的局限性。

关键词： Switchable hydrophilicity solvents   Microextraction   Analytical application   Chromatographic and spectroscopic methods  

摘要： Switchable hydrophilicity solvents (SHS) began being used in analytical chemistry only in 2015, although they have been known for a long time in chemistry and technology. In this review, the advantages of this class of solvents are considered, starting from their effectiveness in the microextraction context. SHS are compatible with chromatographic, spectroscopic (AAS, UV-Vis) and even some electroanalytical (voltammetry) techniques, which allows to determine many organic and inorganic substances in different complex matrices. The chemical analytical characteristics reported over the past 5 years, methods of analysis based on the use of SHS micro extraction, as well as their advantages and disadvantages are presented. Given the positive dynamics of publications with the use of SHS, further development of such methods are expected, primarily in terms of expanding the range of defined substances, using new systems and technical solutions aimed at improving the characteristics of spectroscopic and chromatographic methods of analysis.

关键词： Gold nanorods   Nanocomposites   Synthesis of nanoparticles   Chemical analysis   Spectrophotometry   Luminescence spectroscopy   Raman spectroscopy   Electrochemistry  

摘要： This review summarizes different methods for synthesis and recent analytical applications of gold nanorods (AuNRs) and their nanocomposites. Advantages and shortcomings of the main techniques for the synthesis are discussed. Approaches to improve AuNRs characteristics are also considered. Along with various fields of science, AuNRs are used in chemical analysis for sensitive determination of numerous compounds in diverse objects. Recent trends in the analytical use of AuNRs and their nanocomposites are summarized. Application of AuNRs in spectrophotometry, luminescence and Raman spectroscopy, electrochemistry is described. Basic principles of analytical signal generation and peculiarities of the AuNRs use for each group of methods are pointed out and discussed. Main analytical features of the proposed approaches are represented. (C) 2020 Elsevier B.V. All rights reserved.
