摘要： A method for treating an MTBE-contaminated aqueous solution includes forming an adsorbent by treating fly ash with nitric acid and then doping the resultant acid-treated fly ash particles with AgNO3 and calcining. The adsorbent is used to contact an MTBE-contaminated aqueous solution to adsorb the MTBE and the adsorbent and to form a purified aqueous phase which is then separated from the adsorbent.

摘要： Methods and system relate to in-situ treatment of fluid to remove a heavy metal, such as mercury. The treatment utilizes a sorbent injected into a wellbore and disposed in a flow path of the fluid being produced to above ground. The mercury retained by the sorbent upon contact with the fluid may remain within a reservoir from which the fluid is recovered.
