The paper focuses on designing carefully and carrying out combined teaching methods. Meanwhile, some effective teaching methods, including chemical history teaching, situational teaching and heuristic teaching, are used to cultivate students' interest. In general, the teaching reforms have shown that the educational reform can improve self-learning abilities and cultivate innovation ability of students, and thereby improve the teaching quality of agricultural inorganic and analytical chemistry effectively. 相似文献

Summary The operation of a combined inorganic analytical course designed to be as flexible as possible, and to use the student's time most economically is described. It has been found that students can be interested by carrying out experiments on their own preparations, but that considerable caution is needed in the interpretation of the results because their preparations may vary considerably and in a manner which is not predictable. The advantages and disadvantages of such a course are discussed.
Analytisch-chemischer Unterricht im Laboratorium
Zusammenfassung Ein kombinierter anorganisch-analytischer Lehrgang wird beschrieben, der möglichst flexibel ist und die aufgewendete Zeit nutzbringend einzusetzen erlaubt. Durch Versuche mit eigenen Präparaten wird das Interesse des Studenten geweckt; jedoch ist bei der Auswertung der Ergebnisse Vorsicht geboten, da die Präparate unterschiedliche Zusammensetzung aufweisen können. Vor- und Nachteile eines solchen Lehrganges werden diskutiert.

The implementation of a quality system based on the ISO/IEC 17025:1999 standard is a growing necessity for analytical laboratories to demonstrate their technical competence. In 2001, the Nuclear Analytical Techniques Group of the Argentine Atomic Energy Commission obtained the recognition of the International Atomic Energy Agency in the application of neutron activation analysis and the accreditation by the national accreditation body. The importance of the participation of the group in the Agency's Regional Programme for Latin America, ARCAL XXVI on Quality Assurance in Analytical laboratories is discussed, as well as the activities performed to attain these objectives. Some improvements worth mentioning resulted from the implementation of the quality system and, following the premise of continuous improvement, changes were introduced aiming at the laboratory re-accreditation. 相似文献

The article covers factors that determine fundamental difficulties of chemical phase analysis of a mixture of solid phases of inorganic compounds. Stoichiographic principles and methods, novel for analytical chemistry and leading to the efficient solution of the problems of phase analysis, are discussed. Conditions of the selective separation of mixtures of multiphase multielement solid compounds and principles of the new method, fan-like separation, ensuring the extraction of individual phases from unseparated mixtures, are considered. An idea of a complex method of solving analytical problems by stoichiography methods in proposed. The problem of the multiplicity of objects of analysis is discussed and general principles of the efficient solution of problems of the detection and identification of components of complex mixtures of unknown chemical composition are considered. 相似文献
