Oil contamination in water is one of the big problems for environment and human health which caused by petroleum industries (exploration process, transportation, refinery and utilization). Therefore, finding a proper method for oil/water separation is necessary. Hydrophobic sand as an inexpensive material prepared by oil combustion for oil/water separation. Nano/micro soot was formed on surface of sand easily. The water contact angle (WCA) of sample is about 134° and the prepared sand was characterized by SEM and XPS methods. Hydrophobic sand was utilized as a filter which allows passing oil but prevents to permeate water. The separation time is low and separation system do not need any external force. Sand grains as a substrate are abundant and free, the synthesis process is simple and it is capable to produce in large scale.
