INFLUENCE OF EXTRUSION PREPARATION WAYS OF THE GRAIN ON THE CONTENTS IN IT OF MOBILE FORMS OF HEAVY METALS [№ 5 ' 2005]
The article is devoted to the questions of manufacture of "ecologically safe" forages for animals. The role of ions of metals is examined in the article in physiological processes occurring in an organism of an animal at feeding. In the article the classification is given of the brightest representatives of heavy metals in foodstuff on their prevalence and toxicity. Authors offer to carry out an estimation of a forage "safety" by the original technique developed by them which consists in change observation of the acid-soluble forms contents of heavy metals at their transition from a product to a solution.

VARIANTS OF FIRE AND EXPLOSIVE RISKS ON OIL CHEMICAL OBJECTS [№ 12 ' 2004]
Influence of mineral oil type, area of its flood, time of vaporation, temperature, wind speed on number of creating explosive steam-to-gas phase and magnitude of absolute energy potential of typical technological block - tank of type PBC-1000, was researched in this article. It was recommended to limit an area of possible flood of mineral oil till the size no more than 1500 m2.

INFLUENCE OF NATURE OF AMINE ON EXTRACTION OF RARE - EARTH ELEMENTS BY ITS MIXTURE WITH ALKYLPHOSPHOR EXTRAGENT. [№ 5 ' 2004]
The extraction of rare - earth elements from sulfuric solutions by mixture of extragents di -2 ethilphosphoric acid and primary amine. Synergetic effect by extraction of yttrium by mixture of structure D2EGFK: ANP=4:1. Coefficient of division of pair Ce/La 1,7 times and Y/La 10,5 higher, than individual D2EGFK. Synergetic effect remains in chloride solutions.

RESEARCH OF KINETICS OF IODINE'S SORPTION OUT OF GROUTS BY THE METHOD OF BREAKING. [№ 4 ' 2004]
The results of research of kinetics of iodine's sorption out of grouts with mineralization of 0,5 and 5,0 gram - molecule/ liter by method of breaking are given in the article. The given method allow to define the mechanism and kinetic parameters of limitative stages of iodine's sorption and its polyhalogenide ions. Sorption was made with the usage of highly fundamental ionite AB - 17 - 8 (CL-form) with the diameter of grains 0,63 and 0,40 mm.

POLYHALOGENEDE IONS ABSORBATION PROCESS BY ANIONEXCHANGE ABSORBENTS FROM SOLUTIONS OF DIFFERENT ION STRENGTH [№ 2 ' 2004]
The article considers theoretic aspects of persorption of polyhalogenede ions at high-basic anion-exchanger in different conditions. Salt background and pH value influence are showed in model solutions with salt background concentration from 0.0 to 5.0 mol/l. Na2CO3 trace amounts influence on ion persorption process is considered, also selectivity row of AB-17-8 in Cl- in polyhalogenede ions form is proposed.

EXTRUSION PROCESSING AS "ENVIRONMENTALLY SAFE" PRODUCTION FACTOR OF GOODS FROM GRAIN AND DERIVATIES [№ 2 ' 2004]
The article considers the problem of getting feed-stuffs designed for feeding agricultural animals by extrusion grain wastages processing and VMR from "environmental safety" point of view, which is estimated through heavy metals content in original material and end-product.

RESEARCHES OF PROCESS OF COPPER AND ZINC DESORPTION FROM CATIONIT КУ-2Х8 [№ 1 ' 2004]
Influence of a nature is investigated and concentration of stripping reagents on copper and zinc desorption from cationit КУ-2х8 in strategic and dynamic conditions. Advantages are shown of use of a solution of chloride of sodium in quality of desorbent at extraction of metals from cationit КУ-2х8, sated in process of ion-exchange polishing of quarry solutions of copper - zinc deposit.

THE SORBATION OF IONS OF METALS BY ORGANIC CATIONS FROM RAB-OF-BANK SOLUTIONS [№ 5 ' 2003]
The principle opportunity of the sorbation clearing of ran-of-bank solutions of a deposit of copper-zinc ores from copper, zinc, iron, calcium and magnesium with the use of organic exchangers КU-2х8, Lewatite and КB-4 is shown. It is established, that the application of heavily acidic ionites (КU-2х8, Lewatite) allows to achieve a high degree of extraction of all metals without preliminary preparation of ran-of-bank waters.
