Abstract

Abstract:

Different contents of lauroyl glycine were incorporated into HVI 350 mineral oil and the biodegradabilities of the formulated oils were evaluated on a biodegradation tester. Thereafter, the interaction effect of four factors, i.e. lauroyl glycine content, oil concentration, microbe nutriment composition and oxygen supply, on biodegradation of HVI 350 mineral oil in soil was studied by means of a L9(34) orthogonal test method. The results indicate that lauroyl glycine obviously promotes biodegradation of HVI 350 mineral oil. The biodegradability of HVI 350 oil increases with increasing content of lauroyl glycine while the lauroyl glycine content is smaller than 1.5%. Of the four impact factors, the effect of lauroyl glycine on biodegradation of HVI 350 mineral oil in soil proves to be the most prominent in various biodegradation durations.

Key words: Lauroyl glycine , Mineral oil , Biodegradation , Orthogonal test

摘要： 在HVI 350矿物润滑油中加入不同量的月桂酰基甘氨酸，采用润滑油生物降解性测定方法考察月桂酰基甘氨酸对矿物润滑油生物降解性的影响，并用L 9 (3 4 )正交实验方法研究了月桂酰基甘氨酸质量分数、润滑油质量分数、营养物组成、供氧方法四因素交互作用下润滑油在土壤中的生物降解特性。结果表明，月桂酰基甘氨酸可明显促进HVI 350矿物润滑油生物降解，且当月桂酰基甘氨酸质量分数小于1 .5%时，润滑油生物降解性随月桂酰基甘氨酸质量分数增大而增大。在实验的不同时间内，四因素交互作用下月桂酰基甘氨酸对土壤中润滑油生物降解的影响最为显著。
