Application of Cogon Grass (<i>Imperata cylindrica</i>) as Biosorbent in Diesel-Filter System for Oil Spill Removal

<i>Imperata cylindrica</i>, often known as cogon grass, is a low-cost and useful sorbent for absorbing oil and optimising processes. The effects of temperature, time, packing density and oil concentration on oil absorption efficiency were investigated and optimised utilising one-factor-a...
