X–ray Fluorescence Analysis of Kaolin Clays – Raw Materials for the Production of Metallurgical Alumina https://doi.org/10.22184/2227-572X.2022.12.6.396.403
When introducing high-silicon raw materials into new technological schemes for the production of metallurgical alumina, an important task is the development and organization of input control on a production scale. The main requirements for the analysis in this case are express, multi-element, accuracy and reliability of the results obtained. The method that satisfies all the above requirements is the X-ray fluorescence method of analysis (XRF analysis), which has proven itself well in the analysis of multicomponent geological objects. This work is devoted to the study of the influence of the sample preparation stage and the choice of analysis conditions on the results obtained, as applied to kaolin clays. The attrition time of the samples was determined, the XRF analysis conditions were chosen, the limits of detection and the lower limits of the determined contents were established. The correctness of the XRF analysis results for kaolin clays obtained under the selected conditions was assessed using inductively coupled plasma atomic emission spectral analysis.

Sorption and extraction methods for recovery of noble metals from hydrochloric acid solutions using anion exchanger DIAION™ UBA 120 and trioctylamine with nitrogen-containing functional groups are compared. The conditions of selective recovery of palladium, platinum and gold from model waste solutions containing macrocontents of copper, nickel, iron, lead, selenium, tellurium, as well as chloride-ion up to 200 g / L have been determined.

Brief analysis of the current state of analytical chemistry teaching in leading Russian Universities according to different educational programs: specialty, bachelor’s degree, master“s degree, is presented. The experience of distant student training, acquired and accumulated by analytical chemistry departments in recent years has been generalized. Positive and negative aspects of such form of training are discussed. The nearest plans of the development of the higher education in the country and the changes taking place in this regard in M. V. Lomonosov MSU are considered.

Modern Russian Analytical Laboratory: Learning to Live in a New Way This year, the market for analytical equipment has undergone major changes. Suppliers and consumers have lost the opportunity to continue long-term cooperation with most corporations – world leaders in analytical instrumentation. A large segment of modern technology turned out to be inaccessible to both research scientists and testing laboratories. How to solve the problems that have arisen, how to act in the current situation, how to avoid typical mistakes during the transition period? This article is devoted to these and other important issues.

What Should be a Modern Laboratory Information Management System? https://doi.org/10.22184/2227-572X.2022.12.6.432.438
The experience accumulated by laboratories in the use of laboratory information management systems (LIMS / LIMS) allows us to think about the correct practice of planning their implementation in terms of goal setting based on the current tasks of laboratories, as well as an idea of the medium-term development of laboratory departments and / or companies as a whole. The future vision of LIMS directly depends on the technologies and capabilities that are in demand today, existing development trends and objective limitations that determine the possibility of using LIMS as an automation tool or preparing a basis for digitalization of laboratory units with its help.

Works of M. S. Tswett in the Perception of Colleagues After His Life. To the 150th Anniversary of the Creator of Chromatography https://doi.org/10.22184/2227-572X.2022.12.6.450.459
In 2022, the 150th anniversary of the birth of the outstanding Russian scientist Mikhail Semenovich Tswett (1872–1919) – a physiologist and biochemist of plants, the founder of the chromatographic analysis method. Today, this method has become widespread and is used in many scientific and industrial industries and areas of the economy. The history of the creation of the method is very complex and contradictory. We talked earlier about the attitude to the works of Tswett of his contemporaries, or rather, about the attitude of the scientific community of those years to a colleague with extraordinary abilities and to his scientific views, often ahead of time. In this message, we will talk about the difficult fate of the discovery of chromatography.
