Argon adsorption studies of porous structure of nongraphitized carbon blacks

2009 Annales UMCS Chemistry  
Structural properties of a series of commercial nongraphitized carbon blacks were studied by means of argon adsorption at 87 K and 77 K. The specific surface area of the samples was calculated using the standard BET method. The micropore volume and external surface area were both calculated by the α s -plot method. Pore volume and adsorption energy distributions were calculated numerically by using the regularization method. The above mentioned quantities obtained from argon adsorption
