Abstract
A rapid method was developed for the removal of the aluminium packing and the radioactive microimpurities in it from a radioactive, powdered Fe/Fe2O3, Fe/ target /1–3 mg/ by means of alkaline dissolution. The multicomponent solution is filtered through a G-5 glass filter under conditions of reduced adsorption. The obtained59Fe does not contain the radionuclide impurities present in aluminium.
Abstract
The use of labelled oil is described for tracing the course of the diffusion and of the oil effect on a population of organisms in water biocoenoses.
Abstract
Thermal analysis of polyester and polyamides based on vanillic acid derivative — terephthaloyl-bis-(3-methoxy-4-oxy benzoic) acid has been reported. Different behaviours with the appearance of the thermal degradation, stucturization and carbonization stages were detected. Thermochemical behaviour of polymers under investigation revealed that technical lignin derivative — vanillic acid are a promise for obtaining polymer materials with good properties.
