Experiments were carried out to study the factors influencing modification of activated carbon (AC) and the effect of adsorption of Phosphine (PH3). Impregnated AC was used as a modified adsorbent and its adsorption capacity for PH3 was studied in laboratory. The factors influencing modified AC included the type of adsorbent, the type of impregnant and the concentration of impregnant. The adsorption...
First, the time evolution of O atoms density in the gas phase during the post-discharge of a pulsed N2-O2 DC plasma is studied using a plasma induced fluorescence technique (PIF) where a main long pulse creates the plasma and a shorter one re-excites atoms in the time post-discharge. The surface loss coefficient of O atoms on pyrex, porous silica, porous TiO2 is measured, this latter being a photocatalytic...
