Yes, but what is the cause? Let us suppose that different manufacturing process can lead to difference in the adsorption capacity. OK
There are many factors affect the adsorption:
1-Concentration
2-Temperature and pH
3-Particle size of adsorbate (solute)
4-Contact time between adsorbent and adsorbate
5-Particle size of adsorbent (surface area)
Where factors from 1 to 4 are related to adsorbate where factor 5 is linked to adsorbent. The smaller the particle size, the higher surface area exposed to the solute that leads to more adsorption.
So, we can see that adsorption capacity of M. Indica activated charcoal is 0.076 while the capacity of A. Indica activated charcoal is 0.026.
This difference can be attributed to the internal surface area available for adsorption which is characteristic to each source. The question in this case; if porosity can be a significant factor in adsorption capacity of each source where an equilibrium may be established between the molecules adsorbed in the small cavities and the molecules adsorbed on the surface and this may be a source difference in the manufacturing conditions.
