The results of the incubation laboratory experiment showed that decomposition cyantraniliprole is bi-phasic and rapid in period after application pesticide accompanied by a subsequent slowdown this process. use biexponential equation increased accuracy description dynamics cyantraniliprole, as evidenced static indices. bi-exponential coefficients were used to calculate parameters non-equilibriu...

The geological disposal of spent nuclear fuel may represent a good solution after a thorough risk assessment. In Finland and Sweden, the host rock for geological disposal is crystalline rock and the repository is based on the Swedish KBS-3 multi-barrier design. When radionuclides from spent nuclear fuel are potentially released into the bedrock, they are then transported by advection along wate...

Abstract Based on an analysis of the results original research performed in Laboratory Sorption Methods Vernadsky Institute Geochemistry and Analytical Chemistry Russian Academy Sciences within project “Mathematical Chromatograph,” review covers aim strategy imitation modeling high-performance chromatography; associated problems theory intermolecular interactions; classifications polar stationa...

The disposed wastes of zinc industries contain large amounts of heavy metals such as Pb2+ and Cd2+. These elements are considered as hazardous elements to human beings and other organisms. This study aims at introducing the fungal isolates that evolved to be compatible with waste deposits during the time and can absorb Pb2+ and Cd2+ions. During the spring and autumn in 2011, eight samples of se...

This thesis work is aimed at examining the oxygen atom mixing between common iron(III) oxides and Fe(II)aq solution during the sorption process. First, O labeled iron(III) minerals were used in batch sorption reactors to study the exchange of oxygen atom within the Fe(II)aq – iron(III) oxide system. Results showed a much lesser extent of oxygen mixing than reported Fe mixing from previous studi...

Sorption characteristics of phenanthrene (PHE) were studied on eight soils with organic carbon contents spanning over an order of magnitude using phase distribution relationships (PDRs) at 1 h, 48 h, and 720 h contact times. A new algebraic method was employed to describe the sorption characteristics at different time intervals (between 1 h and 48 h, and 1 h and 720 h). It was found that nonlin...

The sorption isotherm of a multiwall carbon nanotube in paraxylene is investigated through a pressure induced infiltration experiment. The inner space of the carbon nanotubes can be occupied by liquid molecules when an external pressure is applied so that the energy barrier caused by the lyophobic surface is overcome. The infiltration–defiltration curve is highly hysteretic, and therefore a sig...
