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, “Sorbent 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.
