Abstract (en)

[origin: GB2201029A] Novel composition and methods for neutralization and solidification of hazardous acidic spills. A dry particulate composition of varying reaction grades of alkaline compounds and varying grades of absorptive materials may be used to neutralize and solidify acidic spills, solidify the spills and render them harmless. These compositions may be applied to the spills by fire-extinguisher-like delivery devices which spread the compositions on the spills from a relatively safe distance without splattering the hazardous material.
