Experimental samples – Loose adsorbents

Loose adsorbents are solid substances of various chemical composition. They are modified so that they have the largest possible surface area, which is useful particularly for the removal of thin layers of liquids on a large surface. Their drawback is dustiness. While using them, the environment becomes covered in a layer of filth (dust). On the other hand, they have long shelf lives, they are stored in bales.

For the purposes of this experiment, four samples commonly used in practice were utilized. One of them is a natural sorbent (peat) and three are synthetic ones with different chemical composition (Table 1).

All substances and sorption materials were conditioned for 24 hours at a temperature of 24°C and air humidity of 60% ± 5% according to ASTM F716-18, where it is stated to: “Suspend specimens in vapor space without contacting water for not less than 24 h prior to testing”.
