The other adsorbents can be regarded as moderately graded materials. From the data of porosity, it is evident that iron ore (P o = 0.110) is the least and scoria (P o = 0.470) is the highest porous material. From the data of specific density, it is evident that iron ore (γ = 4.30) is the densest, and scoria (γ = 1.32) is the least dense material.
