Publication number: 20080317552Abstract: The present invention provides a method of remediating sediments through the use of coal-, plant-, or wood-derived carbon sorbents (i.e., black carbon). The strategy employs the addition to sediments of coal- and plant- or wood-derived carbon sorbents, so-called black carbon particles like activated carbon, char, charcoal, coal, and coke.

Dolomite quick lime may be used to supply an inexpensive source of the desired calcium and/or magnesium base. The calcium and/or magnesium base may be added before, during or after the addition of the permanganate salt.Type: GrantFiled: October 24, 2000Date of Patent: November 13, 2001Inventor: Daniel W.
