摘　　要：Small amount of lauroyl glutamine was incorporated into HVI 350 mineral oil and the biodegradabilities of HVI 350 mineral oil and the formulated mineral oil in soils were evaluated.Thereafter,the biodegradation kinetic equations for the two lubricating oils were regressed based on the exponential rate model.The results indicated that lauroyl glutamine obviously promoted biodegradation of HVI 350 mineral oil.Under given test conditions,the biodegradation kinetic equation of HVI 350 mineral oil can be described as St=50.4e-0.0155t,while that for lauroyl glutamine formulated oil as St=51.2e-0.0235t.The half-lives of the two lubricating oils were 44.72days and 29.50 days,respectively.Small amount of lauroyl glutamine was incorporated into HVI 350 mineral oil and the biodegradabilities of HVI 350 mineral oil and the formulated mineral oil in soils were evaluated.Thereafter,the biodegradation kinetic equations for the two lubricating oils were regressed based on the exponential rate model.The results indicated that lauroyl glutamine obviously promoted biodegradation of HVI 350 mineral oil.Under given test conditions,the biodegradation kinetic equation of HVI 350 mineral oil can be described as St=50.4e-0.0155t,while that for lauroyl glutamine formulated oil as St=51.2e-0.0235t.The half-lives of the two lubricating oils were 44.72days and 29.50 days,respectively.
