Oil sorption mechanism by natural sorbents


Environment friendly absorbents for oil spill cleanup have become popular over the last few years. Natural fibers such as cotton, wheat straws etc. fulfill the need of an environment friendly absorbent and a low-cost recyclable material after the cleanup. There are several factors which affect the absorption performance including fiber quality, viscosity of oil, temperature, surface tension, etc. This thesis is focused on comparing absorption performance of 3 types of cotton based materials. Absorption capacity which is defined as the amount of oil absorbed (in gram) per unit amount of sorbent (in gram). Experiments with different combination of oils and cotton based materials reveal were undertaken. Modifications were done to ASTM standard to carry out the experiments in scientific robust fashion and more applicable to oil sorption work.
