摘要

Benzotriazole compounds are frequently employed as anticorrosion agents in the process industries, aircraft deicing fluids, and automobile antifreeze. This research assesses the sorption of these compounds to four different soils characterized primarily by total organic carbon content. The compounds investigated were benzotriazole, 5-methylbenzotriazole, and 5-chlorobenzotriazole at concentrations of 10, 20, 50, 100, 200, and 500 mg/l in batch conditions. Benzotriazole compounds are very resistant to biodegradation and toxic to some organisms. The wide use of these compounds causes concern in environmentally preserving a natural habitat. One special concern is the application of aircraft deicer fluid. Typically aircraft deicer fluid is applied to the plane prior to takeoff while on the runway. This fluid may eventually migrate to nearby vegetated areas, in which the benzotriazole compounds are sorbed to the soil. The understanding of this sorption, which can be significant, is difficult due to the sheer complexity of soil and the unique properties of benzotriazole compounds. Additionally, partition parameters such as the octanol-water partition coefficient and Langmuirian parameters were determined for these compounds.
