It is the continuation and promotion of knowledge of analytical chemistry course and the key course to improve the scientific research ability of students. The course includes modern separation science, modern electroanalytical chemistry, modern photoanalytical chemistry and advanced analytical chemistry. It is an important guarantee for improving teaching quality to carry out teaching reform of modern analytical chemistry. In the paper, starting from the construction of teaching team, the modern analytical chemistry course group including four courses was set up for the first time. The course contents are reorganized. The teaching methods are optimized and coordinated. The courses are constructed collectively, including reforming the teaching mode and teaching method, editing textbook appropriately and setting up website with a variety of teaching materials. Therefore, the teaching quality can be guaranteed and the disciplinary fundamentals for research work of students can be strengthened.

新工科背景下分析化学中质量保证和质量控制的教学改革探究*

通过对目前分析化学教学中存在问题的分析,探究了新工科背景下分析化学专业中关于质量保证和质量控制方面的教学改革,提出了增设“分析化学中的质量保证和质量控制”或者类似的课程的建议,指出分析化学的教学应该围绕整个分析过程展开,并将分析化学中的质量保证和质量控制知识融入分析全过程中,注重理论课程与实践课程相互结合的同时更加强调应用性,增强学生的实践能力和分析问题、解决问题的能力。此外,分析化学教学重在“分析”,要与分析实验室/检测机构保持紧密联系,应建立以市场为导向、以技术为核心的教学活动,从而实现为社会不断培养与时俱进的分析人才的教育目标。     

Quantities and units in analytical chemistry

Analytical chemistry is largely concerned with the determination of the composition of mixtures. The result of the analysis of a component in a mixture should comprise the product of a ‘numerical value’ and a ‘unit’ in order to express the value of the ‘quantity’ being measured (and an associated statement of uncertainty). The quantities and units which can be used to express these results are subtly different and can often be confused and misused. This article clarifies their meaning, presents a novel method of demonstrating the relationship between them, and discusses the advantages and drawbacks of their usage in analytical chemistry, particularly with respect to environmental analysis. Suggestions for best practice for use in analytical chemistry are also made.

Green chemistry: Analytical and chromatography

Nowadays, the environment protection and the personal health and safety are given more consideration in the field of chemistry, thus resulting in an increased number of published researches about how to work according to green instructions, to follow up the recommendations of environmental agencies and to obtain better clean handling of chemistry. In this review, green chemistry definition, importance, principles, and some recent applications in the field of green chemistry were discussed. In addition, the review summarizes the evolution of green analytical chemistry (GAC) with its specific principles and how to make the analytical process more environmentally benign with special emphasis on recent applications of GAC. Moreover, the green chromatography, its methods, and some of its applications were outlined. Finally, different techniques available up till now for the assessment of greening of the methods were also presented.     

Green procedure using limonene in the Dean-Stark apparatus for moisture determination in food products

In the past 10 years, trends in analytical chemistry have turned toward the green chemistry which endeavours to develop new techniques that reduce the influence of chemicals on the environment. The challenge of the green analytical chemistry is to develop techniques that meet the request for information output while reducing the environmental impact of the analyses. For this purpose petroleum-based solvents have to be avoided. Therefore, increasing interest was given to new green solvents such as limonene and their potential as alternative solvents in analytical chemistry. In this work limonene was used instead of toluene in the Dean-Stark procedure. Moisture determination on wide range of food matrices was performed either using toluene or limonene. Both solvents gave similar water percentages in food materials, i.e. 89.3 ± 0.5 and 89.5 ± 0.7 for carrot, 68.0 ± 0.7 and 68.6 ± 1.9 for garlic, 64.1 ± 0.5 and 64.0 ± 0.3 for minced meat with toluene and limonene, respectively. Consequently limonene could be used as a good alternative solvent in the Dean-Stark procedure.
