Diffusion mechanism of water vapour in a zeolitic tuff rich in clinoptilolite
The adsorption kinetics of H2O in a clinoptilolite rich zeolitic tuff was experimentally investigated at 18°C. In the identification of the diffusion mechanism the isothermal adsorption model equation was used. It was found ...
Kinetics of proton transfer in the zeolitic tuff
(Central European Science Journals, 2009)
The kinetics of a proton transfer into dilute acid solutions containing natural zeolitic tuff was studied by following the pH evolution of the liquid phase. Four different solutions with tuff contents of 9, 3, 1 and 0.5 ...
