| 摘 要： | 在HVI 350矿物润滑油中加入少量月桂酰基甘氨酸,对比研究了加入月桂酰基甘氨酸前后矿物润滑油在土壤中的生物降解特性,并采用指数速率模型对润滑油生物降解动力学进行了模拟.结果表明,月桂酰基甘氨酸可促进HVI 350矿物润滑油生物降解,试验条件下HVI 350矿物润滑油生物降解速率方程为S_t=50.4e~(-0.0155t),半衰期为44.72 d;含月桂酰基甘氨酸的HVI 350矿物润滑油生物降解速率方程为S_t=51.6e~(-0.0224t),半衰期为30.94d. |

| Abstract: | Small amount of lauroyl glycine was incorporated into HVI 350 mineral oil and the biodegradabilities of HVI 350 mineral oil and the formulated oil in soils were evaluated. Thereafter, the biodegradation kinetics of the two lubricating oils was regressed based on the exponential rate model. The results indicated that lauroyl glycine obviously promoted biodegradation of HVI 350 min-eral oil. Under given test conditions, the biodegradation rate equation for HVI 350 mineral oil could be described as S_t = 50.4e~(-0.0155t), while that for lauroyl glycine formulated oil as S_t= 51.6e~(-0.0224t). The biodegradation half-lives of HVI 350 min-eral oil and the formulated oil were 44.72 days and 30.94 days, respectively. |
