The effect of a number of inorganic and organic compounds on the extractability of /sup 239/Pu from a contaminated soil has been examined. This has been done on an artificially contaminated kaolinitic soil by using the equilibrium batch method of extraction. Among the 21 inorganic compounds examined, NaHPO/sub 4/ showed the least /sup 239/Pu extractability (0.07 percent of dose) and Na/sub 4/P/sub 2/O/sub 7/ showed the greatest extractability (28.59 percent of dose). The compounds that showed relatively high /sup 239/Pu extractability included NaF, Na/sub 2/B/sub 4/O/sub 7/, Na/sub 4/P/sub 2/O/sub 7/, Na/sub 2/CO/sub 3/, Na/sub 2/O/sub 2/, NaOH, and NH/sub 4/OH. Among the organic compounds, the order of /sup 239/Pu extractability was Na acetate less than Na formate less than Na oxalate less than Na tartrate less than Na citrate. A 0.004M DTPA solution was a more effective extractant than a 0.08M citric acid solution. Aside from the chemical nature of these compounds, the /sup 239/Pu extractability was influenced by soil and extractant pH, soil organic matter, equilibrium time, soil weight/extractant volume ratio, and wet-dry pretreatment of the soil.
