Vegetable Oil and Motor Oil Adsorption/Absorption Capacity Analysis by Weight

Tests were performed on ADsorb-it® sorbent media to determine its capacity to sorb oils.

Method

The tests were performed using guidelines described in ASTM Method F726-81, ‚ÄúSorbent Performance of Adsorbents." This test method measures the maximum adsorption of oils and floating immiscible liquids. The materials tested were representative samples of ADsorb-it® bulk material. The oils used were 30W motor oil and a liquid vegetable oil. Three replicates were performed for each type of oil.

Conclusions

The bulk ADsorb-it® material adsorbed 17 times its weight in vegetable oil and 20 times its weight in motor oil.
