摘要： A method of treating or remediating contaminated material, such as water or soil, comprises contacting such material with asphaltenes. The asphaltenes are preferably produced as a by-product of petroleum refining and, in particular, a by-product of vacuum residua. An adsorbent material comprising such asphaltenes is also provided.
