Abstract
Official abstract text for this publication.
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-contaminated solid surface to remove the mercury contamination.
First claim
Opening claim text (preview).
What is claimed is: 1.
