What are the differences between adsorption and absorption ?
Adsorption and absorption can be distinguished as follows:
Adsorption | Absorption |
1. It is a surface phenomenon 2. In this process particles of gas and liquid accumulate only on the surface of a solid
3. The rate of adsorption is high initially and decreases with time. | 1. It is a bulk phenomenon 2. In this process particles of gas and liquid enter through the surface and gets uniformly distributed throughout of solid. 3. The rate of absorption is same throughout. |
