    A method for processing of rice wastes (husk, straw) into activated carbon was proposed. The thermolysis of raw material and the activation of carbonizate were carried out at 500oС and 800oС temperatures respectively. The properties of obtained activated carbon are determined by standard methods. The porous structure of obtained carbon have been studied under scanned electronic microscope. According to the results of experimental studies, activated charcoal obtained from rice husks corresponds to the WAC brand, activated charcoal obtained from rice straw corresponds to BAU-A grade. The research will allow rational use of agricultural waste in order to obtain useful secondary adsorbent products intended for adsorption and liquid media.

    Carrying out joint activities in order to obtain a widely used adsorbent – activated carbon. A carbonization tube in a tube furnace made of stainless steel at a temperature of 500°C, and activation of a carbonizate carried out by steam at a temperature of 800°C. The influence of the ratio of the initial components of the raw material (husk:oil sludge) on the properties of the product was studied. Husk:oil sludge is 9:1 (by weight), respectively. Indicators such as water adsorption activity, total owner volume and bulk figure were studied. The microstructure of the obtained activated carbon was studied on a scanning electron microscope. 9: 1 corresponds to activated carbon brand DAK. References [1] Kinle H., Bader Je.

    Background Rapid technological advancement, digitalization of analytical instrumentation, and the growing demand for interdisciplinary competence have significantly transformed the role of analytical chemistry in science and industry. These changes necessitate a systematic reconsideration of how physicochemical analysis methods are taught within continuous chemical education. Objective This scoping review aimed to map and systematize the structural components of modern analytical chemistry education, identify dominant pedagogical approaches, and conceptualize their functional interrelationships within an integrated educational framework. Design/methods The study was conducted as a scoping review in accordance with PRISMA-ScR guidelines. A comprehensive search was performed in Scopus, Web of Science, ScienceDirect, ACS Publications, SpringerLink, and RSCI (eLIBRARY.ru), covering publications from 1975 (the earliest eligible record retrieved) to 2024. Eligible studies addressed pedagogical, curricular, or methodological aspects of teaching analytical chemistry or physicochemical analysis methods. Extracted data were analyzed using qualitative thematic synthesis and conceptual mapping to identify recurring educational components and trends. Results The analysis revealed a consistent shift from method-centered instruction toward competence-oriented and system-based educational models. The most frequently reported components included integration of theoretical principles with laboratory practice, problem-based and research-oriented learning, incorporation of digital tools and chemometrics, emphasis on metrology and data interpretation, and increasing attention to sustainability and green analytical chemistry. The evidence indicates a transition from isolated presentation of analytical techniques to structured training focused on analytical thinking, decision-making, and interpretation of complex data. Conclusions Modern analytical chemistry education is evolving toward an integrated, interdisciplinary, and competence-driven model that prioritizes conceptual understanding, information processing, and real-world problem solving. The structural framework identified in this review may support curriculum development, modernization of laboratory courses, and alignment of educational programs with contemporary scientific and industrial demands.
