It is established that the content of lanthanum and neodymium accumulated in plant roots is several times higher than their content in the top mass. Rare-earth elements are most actively accumulated in pea roots. With respect to the coefficients of biological absorption, lanthanum and neodymium are characterized by low and middle level of absorption in the top mass of corn and pea.

On the basis of the data of IR spectroscopy and X-ray phase analysis, it was established that poly-N-vinyl pyrrolidone enters chemical interaction with organic acids during their joint mechanical activation. The character of this interaction depends on the nature of an acid but does not depend on the type of activator, while the duration of the interaction depends both on the nature of an acid and on the type of activator.

The mineral and microelement composition of gallstones extracted from patients in the Novosibirsk and Omsk Regions were investigated. It was stated that a common feature of choleolithiasis in the regions under comparison is noticeable predominance of cholesterol gallstones. It was shown that the prevailing element in gallstones is calcium, while differences in content and distribution of microelements in gallstones is determined by regional features. It was established that the main elements of bile are sodium, potassium and phosphorus, which is in good agreement with literature data.

Outlook for application of amorphous sorbents on the basis of titanyl hydrophosphate to decontaminate liquid radioactive wastes from  137Cs, 134Cs, 90Sr, and 60Co radionuclides with elevated (up to 32 g/l) salt background that corresponds in composition to see water has been shown. Impurities in the form of petroleum derivatives (up to 0.4 g/l) and solid suspensions have no considerable effect on the deactivation and they can be separated together with the waste sorbent from the being cleared solution. The flow chart for the decontamination has been suggested. Heat treatment of the waste sorbent enables conducting immobilization of radionuclides within a solid phase. A variant of deactivation of soils that are polluted by radionuclides has been suggested.

Investigation of a series of fine powders of the copper alloy with the addition of 15 mass % tin,
4 mass % nickel and 5 mass % phosphorus was carried out by means of X-ray photoelectron spectroscopy. It was shown that the chemical composition of subsurface layers of powder particles of the solder depends on preparation procedure and affects the quality of soldering.

Compounds of Pd(II) of the PdL2 formulation with perfluorinated thiols of aromatic series 4-CF3C6F4SH (HL1), 2,4-(CF3)2C6F3SH (HL2), 4-nonafluorodiphenylthiol C6F5C6F4SH (HL3), 2-heptafluoronaphthalenethiol C10F7SH (HL4), and phenolic antioxidant 2,6-di(tert-C4H9)-4-(CH2)3SH (HL5) have been obtained that feature a rather weak smell for mercaptans. The HL3 structure has been determined by the X-ray diffraction analysis method. Thermal properties of Pd(L1)2

Pilot trials of a new nanocomposite mesopore sorbent of the NCMS type have been conducted in a purification technology for slightly acidic sewage from mercury. According to the trials, the dynamic capacity with respect to mercury of the NCMS sorbent was equal to 25.6 mg/g. Atomic emission spectroscopy method with the application of a two-jet plasmatron and a registration scheme was used to receive data on the nature of quantitative distribution of mercury and associated impurity-metals (lithium, sodium, potassium, and calcium) across the layers of a sorbent load. It has been demonstrated that the NCMS sorbent concentrates preferentially mercury and potassium, and their mutual ratio is close to the formulation of K2HgI4 compound, while impurities of other metals practically do not accumulate in the sorbent.

Physical and chemical composition of the stored waste wood taken from the pits of the Ust-Ilimsk Timber Industrial Complex (TIC) was investigated. The microbiological and sanitary-hygienic status of the waste wood was examined. The experimental data obtained provide evidence that the mass in the pits is friable because of large-size wastes, so oxygen access is provided even to the deep layers in the pit. Aerobic microorganisms (fungi and bacteria) that had occupied the lowest old layers have already created a united community that carries out biochemical destruction of waste wood forming ecologically dangerous lignin-like substances, neutral compounds, phenols and acids. Intense microbiological activity can lead to spontaneous ignition of waste wood, which belongs to the class of fire dangerous substances.

It has been demonstrated that introduction of caprone fibre in SKS-30 ARK latex makes it possible to reach its uniform distribution in the polymeric matrix and to increase a yield of coagulum. The availability of interfacial interaction between the surface of the fibre and styrene butadiene rubber matrix has been found. The introduction of caprone fibre makes it possible to enhance the vulcanizate resistance to heat ageing, repeated strains, and tear.

The possibility of a substantial decrease in the amount of industrial wastes by supplementing the technological process with the stages performed by means of electrolysis was demonstrated for the examples of processes of isolation of elemental arsenic from the aqueous solutions of sodium arsenite, syntheses of the esters of phosphic acid from elemental phosphorus, obtaining arsenic acid by the electrolysis of a suspension of arsenic (III) oxide, synthesis of azodicarbonamide, ketopanlactone and arsine.
