@entity49386 addition to soil at a remediation site was observed to sufficiently reduce @entity4966 levels, but the cause of the removal could not be confirmed with the field data collected. Potential mechanisms for @entity25053 treatment of @entity4965 ( @entity4966 ) in soil include degradation and volatilization. Since earlier studies found @entity4966 degradation to occur during the hydration of @entity25053 under conditions where volatilization was limited, research was conducted on mechanisms of @entity4966 removal from soil by @entity25053 application under conditions where volatilization was allowed to occur. @entity4966 volatilization in soil treated with 0%, 5%, 10%, and 20% @entity25053 doses was measured in experiments where the degree of volatilization could be tracked. The total @entity4966 removal from soil spiked with @entity4966 at @entity25053 doses from 5% to 20% ranged from 97% to 99% of the initial @entity4966 mass. Volatilization accounted for 64.4-92.5% of the @entity4966 removal, with unrecovered @entity4966 and @entity4966 degradation accounting for the remaining fraction. The greater heat encountered with higher @entity25053 doses helped minimize obstacles to @entity4966 volatilization, such as high soil organic and clay content. Treatment with a 20% @entity25053 dose, however, led to the formation of byproducts such as @entity72651 . @entity4966 degradation to @entity72651 at the 20% @entity25053 dose ranged from 2.7% to 6.4% of the initial @entity4966 . Volatilization was concluded to be the dominant process for @entity4966 removal from soil during @entity25053 treatment.
