METHOD FOR REMOVING MERCURY CONTAMINATION FROM SOLID SURFACES

A method of selecting a mercury-contaminated solid surface followed by heating a cleaning solution to a temperature less than 100° C. The cleaning solution can contain hydrocarbon oil and one or more organic sulfur compounds. Afterwards, the heated cleaning solution is contacted with the mercury-con...
