The present investigation aims at estimating the biodegradation coefficients of surfactants. The biodegradabilities of Triton X-100 and Rhamnolipid were tested under aerobic, nitrate reducing, sulphate reducing and anaerobic conditions using a respirometer. The results indicated that in terms of biodegradability, Rhamnolipid is superior to Triton X-100, since it is biodegradable under all conditions, whereas Triton X-100 is partially biodegradable under aerobic conditions and non-biodegradable under anaerobic, nitrate reducing and sulphate reducing conditions.
本研究旨在估算表面活性剂的生物降解系数。使用呼吸计在好氧、硝酸盐还原、硫酸盐还原和厌氧条件下测试了Triton X-100和鼠李糖脂的生物降解能力。结果表明，就生物降解性而言，鼠李糖脂优于Triton X-100，因为它在所有条件下都可生物降解，而Triton X-100在好氧条件下部分可生物降解，在厌氧、硝酸盐还原和硫酸盐还原条件下不可生物降解。
