Considering light absorption by narrowing the band gap and gas capture by the mesostructure and basicity of material, an efficient artificial photosynthesis system was constructed based on a mesoporous ZnAl(2)O(4)-modified ZnGaNO photocatalyst.
We describe a rapid method for determining light halogenated hydrocarbons (LHH) in urine by electron capture gas-liquid chromatography. The hydrocarbons are extracted from urine into pentane. A 2-microliter injection of the pentane extract provides a detection limit of less than 1 microgram/liter.
a modification of peng-robinson equation is described wherein in the parameter b is expressed as a linear function of temperature. the modified equation is then applied to a series of light hydrocarbons and refrigerants, and predicted values for vapor pressure, saturated vapor volume, saturated liquid volume and the heat of evaporation are compared with the corresponding experimental data. cons...
In this paper, the ability of chrome shavings to remove motor oils, oily wastes and hydrocarbons from water has been studied. To determine amount of hydrocarbons sorbed on tanned wastes, a FT-NIR methodology was used and a multivariate calibration based on partial least squares (PLS) was employed for data treatment. The light density, porous tanned waste granules float on the surface of water a...
Background and Aims: Nowadays, soil pollution with total petroleum hydrocarbons (TPH) is one of the major environmental issues caused serious problems to human and other living organisms. One of the best and most reliable methods of bioremediation is the use of earthworms known as vermin-remediation. In this study, bioremediation of gasoline-contaminated soil using Eisenia Fetida, the mixture o...
