Abstract
The biodegradation of linear alkylbenzene sulfonate (LAS), α-olefine sulfonate (AOS), and alcohol sulfate (AS) were examined under the low dissolved oxygen (DO) condition. Also the accumulation of LAS in sediments was determined.
It was showed that these surfactants were biodegraded enough under the condition of less 1 mg/l of DO concentration. Especially AOS and AS were biodegraded very easily. LAS is able to adsorb on sediments in rivers and lakes, but not accumulate so long time because of its biodegradability under the low DO condition.
