The problems of galvanic production waste recovery, conditions, influencing on the final tailings composition, influence of the chemical composition of final tailings on the ways of their recovery are examined

INFLUENCE OF COLLOID-CHEMICAL STATE OF HEAVY METALS IONS ON MORPHOLOGY AND PHASE COMPOSITION OF THEIR OXIDE CONFIGURATIONS (COMPOUND Al3+)

The influence of colloid-chemical state of ions of heavy metals on morphology and phase composition of their oxide modes (compound Al3+) is shown

MODERN TENDENCIES OF THE PAINTWORK PRODUCTION APPLICATION IN MACHINE-BUILDING PRODUCTION

The data is generalized and the tendencies of using of organic solvents in 2001-2005 as compared to the period of 1997-2000 are determined in the present work

PROSPECTS FOR THE USE OF WASTE OILS AS ALTERNATIVE FUEL IN TECHNOLOGICAL PROCESSES OF MANUFACTURING OF CASTINGS AND FOUNDRY MOLDS

Quantitative and qualitative composition of the gas emission has been investigated. Quantity of CO, СО2, NOx, О2, paraffin hydrocarbons and benzene derivatives in the reaction zone depending on the duration of the process and temperature 400–800 ºС has been determined. The list of organizations utilizing waste oils as alternative fuel is presente

THE WATER PURIFICATION SYSTEM OF MACHINE-BUILDING COMPLEX FROM OIL-PRODUCTS

The developed system of purification of sewage water from petroleum products allows to provide efficiency of purification up to the norms of PDK, and if necessary the devices can be used as a separate modules or their combinations

Porous structure of intercalated cobalt ferrocyanides

Radiation safety is an integral part of environmental safety and includes a set of measures to protect people and the environment from the harmful effects of ionizing radiation. Ferrocyanides of transition metals are among the most highly effective and selective collectors for concentrating radionuclides. Under certain conditions of synthesis, ferrocyanide compounds can be formed having a layered structure, for example, the ferrocyanide 2Co2[Fe(CN)6] K4 [Fe(CN)6] 3H2O, however, taking into account the structure of the starting material it was decided to use Fe3+ polyhydroxy complexes as a modifying agent. The effect of the amount of modifiers on the sorption properties of cobalt ferrocyanide was studied in the course of the work

INFLUENCE OF COLLOID-CHEMICAL STATE OF HEAVY METALS IONS ON MOФHOLOGY AND PHASE COMPOSITION OF THEIR OXIDE FORMS (Fe)

The influence of colloid-chemical state of ions of heavy metals on morphology and phase composition of their oxide forms (compounds Fe) is considered

INFLUENCE OF COLLOID-CHEMICAL STATE OF HEAVY METALS IONS ON MORPHOLOGY AND PHASE COMPOSITION OF THEIR OXIDE FORMS (COMPOUNDS Co and Cd)

The speed of β-Cd(ОН)2 dehydration is studied. It is shown that at 300 °C and higher β –Cd(OH)2 dehydration with forming of the product of composition CdO0,8 occur

APPRAISAL OF FINAL TAILINGS APPLICABILITY FOR PROCESSING AND PRODUCTION OF MODIFIERS OF IRON-CARBON ALLOYS
