Some solute transport attenuation properties of the Bunter sandstone, England.
Laboratory parameters of secondary mechanisms of pollution such as porosity, density, primary permeability, formation factor, and diffusion exhibited good correlating straight line relationships for triassic Sherwood sandstone. These relationships supported the hydrogeopollution studies of the porous medium and revealed its good uniformity and homogeneity suitable for mathematical formulation. For the study of the mechanisms of attenuation, such as rates and heats of adsorption, static equilibrium techniques were employed with satisfactory results. Concerning toxic metal pollutants, exothermic reactions were involved with Freundlich-type isotherms. With most heats of adsorption found to be less than 8 kcal mol-1 (physical adsorption), and due to the high values of distribution coefficients, the formation proved to be an excellent retardation unit for the disposal of toxic metal pollutants.
