A Improved Method for Study on Biodegradation of Castor Based Lubricants

Abstract:

. A castor oil-based detection method for the analysis of biological degradation was established on the base of CEC-L-33-A-93 test method and the domestic conventional experimental methods. Difference of the test samples between the experimental and published values was less then 0.50%. Maximum error of degradation rate was 1.92% in parallel experimental. Compared to the domestic conventional methods, degradation rate obtained by the improved analysis methods of castor oil-based is approximately higher than 5.0%. Meanwhile, analysis and detection method of DIOS with advantage of high accuracy, conveniency and good reproducibility is established and showed stability by studying the correlation of parallel samples that the coefficient of variation is less than 5%.
