The Impact

Study of macro- and microelement composition of the ash of plant raw materials revealed the prevailing matrix elements, their chemical form and content. It is shown that direct determination of the impurities in mineral residues by the method of arc atomic emission spectroscopy with a multichannel analyzer of emission spectra (MAÉS) is complicated by the impact of the macro component and its chemical form on the intensity of the spectral lines of the impurities. Introduction of a corrective additive is proved to eliminate this effect. A technique for measuring the mass fraction of macro elements and trace elements in plant ash is proposed and metrological certification of the procedure is carried out.

The Impact

The impact of Taldan crushed stone plant and wastes formed in process of its activity on the environment is considered. About 2.9 million tons of siftings of rock grinding were accumulated in dump massifs with a total area of 600 hectares. Therefore, elimination of accumulated harm to the environment that has arisen over many years of operation of Taldan crushed stone plant is the actual task. One of the technological solutions of liquidation of objects of accumulated harm to the environment based on physicochemical impact on wastes is stabilization or artificial stone formation. Drawing of siftings of rock in soil concrete compositions (artificial stone materials) allows to solve complex of acute environmental problems due to their largetonnage direct use. The use of siftings of rock in road building will contribute to the rational and cost-effective use of natural mineral raw materials, since this process will not entail an increase in the costs of its extraction and processing. A set of modern methods (atomic-emission spectrometry with inductively coupled plasma, scanning electron microscopy, X-ray phase analysis, infrared spectroscopy) were used to study the chemical, phase composition and properties of siftings of rock to substantiate the possibility of its utilization in the composition of soil concrete. It is shown that the introduction of an 8 wt. % of mineral binder and polymer stabilizing additive Element (1, 5, 10 wt. %) allows to get soil concrete with a mark of strength М100.

A Method was studied for the determination of Al、Cu、Ni in Zr-based amorphous alloy by inductively coupled plasma atomic emission spectrometry (ICP-AES). Samples were dissolved by hydrochloric acid,nitric acid and hydrofluoric acid,analytical spectral lines for aluminum,copper,nickle are 308.215nm,327.396nm and 231.604nm.Interference of zinc was eliminated by the matrix-matching method, the experiments were done with optimized Operating Parameters. The correlation coefficients of the calibration curve are all 0.999,detection limits are 0.0010%,0.005% and 0.0006% respectively,and the range of recovery is 98%-104%.

Active Substances

Using the methods of arc atomic emission spectrometry (AAES), atomic emission flame photometry (AEFP), atomic absorption spectrometry (AAS) and mass spectrometry (ICP-MS), the elemental composition of the aerial part of widely used in medical practice Alfredia cernua and Filipendula ulmaria, extracts and fractions obtained from them, is investigated. It was shown that not only biologically active substances, but also mineral elements are extracted by extractants, which may be due both to the formation of complexes with biologically active substances and affinity for extractants. Therefore, the elemental composition must be considered as an important component of plant extracts and medicinal products obtained from them. Simultaneously with biologically active substances in ethanol extracts there is an accumulation of not only biogenic, but also toxic elements, which degree of extraction is often higher. It increases even more during the transition from periodic to countercurrent extraction, which allows to obtain extracts with the highest yield of biologically active substances. Since the enriched extract is directly used to obtain the dosage form, a preliminary elemental analysis is necessary. Analytical control of the content of TM is also necessary when choosing the place of growth of plants raw materials, which are used to create medicinal herbal remedies.
