Optimization for determination of Linear Alkylbenzene Sulfonate(LAS) and AlkylbenzeneSulfonat (ABS) from biodegradation by Pseudomonas Aeruginosa bacteria

摘要

LAS and ABS are the detergent active compounds and their presence should always be monitored because they are pollutants. Detergent treatment has been done by way of adsorption, flocculation, coagulation and advanced oxidation, but the process can produces unwanted sludge that need further processing. One alternative technology that is used to treat wastewater is biological treatment using the bacteria Pseudomonas aeruginosa, because this method was easier and very economical when compared with other processing methods. Before, biodegradation by Pseudomonasaeruginosa is done only for the treatment of LAS but on this study it is also conducted for the treatment of LAS and ABS. So it is necessary to determine optimum conditions. With this method LAS and ABS was degradable to CO_(2) and H_(2)O.? In this study, LAS and ABS successfully degraded 99.73%. With the longer time CO_(2) formed was increasing, and the biggest CO_(2) at pH 7 and the 50th hour, concentration of CO_(2)was127.6 mg / L.
