关键词： 分析化学   课程思政   教学改革  

摘要： 课程思政是新时代高校思想政治教育的创新理念,是高校课程教育发展的必然选择。分析化学作为高等院校化工、制药、新能源等多个专业的必修课程,其中蕴含着丰富的思想政治元素。本文以分析化学为例,分析了在该课程中实施课程思政的必要性,提出了实施途径并对实施结果进行了评价和思考,从结果可以看出课程思政为专业课成为“德育”的有效载体提供了理论指导与方向。

关键词： 乙酰水杨酸   直接滴定法   返滴定法  

摘要： 乙酰水杨酸含量测定的实验是医药院校本科生分析化学实验开设的一个常规实验项目,该项目在分析化学实验规划教材中所选用的方法是直接滴定法,此方法也是中国药典收录的经典实验方法。由于该方法所需用的试剂和操作具有一定的危险性,文章通过实践对该实验项目进行方法改进,采用返滴定法进行乙酰水杨酸的含量测定,改进后的方法可操作性强,同时因为不需使用中性乙醇,避免危险性的发生,更适合多人同时进行实验,空白实验的操作更能提高学生的分析思维能力,因而该方法可在常规本科分析化学实验项目中使用。

关键词： 分析化学实验   线上线下混合教学   疫情  

摘要： 为应对新冠疫情对高校工科基础实验课的影响,响应教育部提出的“停课不停学”的号召,开展分析化学实验课线上教学。以酸碱滴定实验为例,提出一种线上线下混合教学案例,提倡“知识线上学,实验家中做”的教学方式。以培养学生实事求是的科学态度,独立思考、独立进行实验的实践能力和分析问题、解决问题的能力,为工科基础实验课特殊背景下的教学模式提供参考案例。

关键词： Analytical method   Assessment tool   Green analytical chemistry   RGB model   Sample preparation   Sustainable development  

摘要： The concept of White Analytical Chemistry (WAC) is presented as an extension of Green Analytical Chemistry (GAC). We propose the 12 WAC principles as an alternative to the known 12 GAC principles. In addition to green aspects, WAC takes into account other key criteria affecting the quality of the method, analytical (red) and practical (blue). In reference to the RGB color model, according to which mixing of red, green and blue light beams gives the impression of whiteness, a white analytical method shows the coherence and synergy of the analytical, ecological and practical attributes. Whiteness can also be quantified, based on the assessment of individual principles, as a convenient parameter useful in comparisons and selecting optimal method. WAC is closer to the idea of sustainable development due to a more holistic view, as it strives for a compromise that avoids an unconditional increase in greenness at the expense of functionality.

关键词： Upper-Level Undergraduate   Analytical Chemistry   Environmental Chemistry   Undergraduate Research  

摘要： This article reports on the implementation of a CURE project in an upper-level analytical chemistry course to engage a larger number of students in research at a primarily undergraduate institution (PUI). The lab course syllabus was modified to provide students with an opportunity to experience the process of conducting research through a project that was relevant to them personally and the community at large. Students carried out research using microwave plasma atomic emission spectroscopy (MPAES) to correlate lead levels in soil with home location, source, and age. Students' self-assessment and surveys suggest that implementing a research project that students can relate to leads to an increased level of mastering analytical skills and demonstration of a higher level of critical-thinking skills. Participation in the CURE project increased a desire and a commitment to engage in independent research and in communicating science through presentations.

摘要： We have revamped a classic analytical chemistry laboratory experiment, "Determination of an Unknown Acid", to provide students an opportunity to learn about new advances in the material sciences and their applications in analytical chemistry in an effort to reinforce the key concepts of chemical analysis. Specifically, students were given the opportunity to develop their own low-cost, low-maintenance, ease-of-use, multidimensional pH sensor with intrinsically conducting polyaniline material. The students tested their polyaniline pH sensor against the traditional glass pH electrode to determine an unknown acid concentration and performed statistical tests to validate the analytical capabilities of their electrochemical polyaniline pH sensor. Thus, the revamped laboratory experiment allows for the reinforcement of several fundamental analytical chemistry lecture concepts, including chemical analysis, method development, validation, and statistical practice utilizing a more cohesive hands-on laboratory learning approach. Furthermore, this revamped lab gives students the opportunity to evaluate and compare the analytical performance of the polyaniline pH sensor, such as its sensor lifetime against the glass pH electrode, and learn polyaniline's electrochromic properties. This laboratory experiment can be easily disseminated to advance the objective of analytical curriculum, provide students an opportunity for multidimensional learning and well-connected critical thinking in analytical chemistry, and stimulate students' creativity in developing next generation analytical sensor technology.
