Adsorption/Absorption Capacity: Motor Oil and Vegetable Oil
Introduction- Tests were performed on X-TEX sorbent media to determine its capacity to sorb oils.
Method- The tests were performed using guidelines described in ASTM method F726-81, “Sorbent Performance of Adsorbents”. This test method measures the maximum adsorption of oils and floating immiscible liquids. The materials tested were representative samples of X-TEX bulk material. The oils used were 30W motor oil and a liquid vegetable oil. Three replicates were performed for each type of oil.

| Bulk 2 | 3.3 | 72.33 | 21.9x |
| Bulk 3 | 3.46 | 69.1 | 20.0x |
Conclusions- The bulk material adsorbed 17 times its weight in vegetable oil and 21 times its weight in motor oil.
