The analytical method development on an anionic surfactant of sodium dodecylbenzenesulfonate (SDBS) in a catfish using spectrophotometer UV-Vis using acridine orange (AO) has been conducted. This research aims to determine the optimum conditions of analysis and to determine validation parameters of sodium dodecylbenzenesulfonate (SDBS) analysis in a catfish. This study was divided into two steps, isolation of sodium dodecyl benzene sulfonate (SDBS) in the catfish with soxhlet extraction and the analysis of SDBS. The analysis of sodium dodecylbenzenesulfonate (SDBS) is based on the formation of ion pair between dodecylbenzenesulfonate (DBS) and acridine orange (AO). The results showed that the analysis can be performed at 499 nm, using ethanol as acridine orange (AO) solvent, the mole ratio of dodecylbenzenesulfonate (DBS) acridine orange (AO) 2:1, and pH 2.97. The parameters of validation had good acceptability as linearity (r) 0.998, limit of detection 0.0343 mg/L   and limit of quantification 0.104 mg/L, precision 0.382 - 1.78 %, sensitivity 4.64 x 10<sup>4</sup> L mol<sup>-1</sup>cm<sup>-1</sup>, and accuracy (82.11 - 100.3 %).

Polyethylene Oxide (PEO) is one of the most common drag reduction agents. However, its ability to reduce drag in turbulent flow decreases with the time due to the degradation of its molecules. Thus, the enhancement of its degradation resistance by the addition of Anionic surfactant is presented. The Polyethylene oxide (PEO) was used in different concentration ranges from 10 to 60 ppm and with addition of sodium dodecyl benzene sulfonate (SDBS) as the anionic surfactant with five concentrations between 100 to 500 ppm. The degradation measurements were done using rotating disk apparatus (RDA). The RDA results have shown a considerable improvement in the degradation resistance of PEO with the addition of surfactant to the polymer solution. The interaction between the polymer and the surfactant results in transferring the polymer chain from coil to straight-like body. Thus, enhance the polymer degradation resistant ability.

A surface properties of a sulfobetaine–type zwitterionic gemini surfactant with the structure of 1,2-bis [N-methyl-N-(3-sulfopropyl) -dodecylammonium] ethane betaine (ZGS12), were investigated in aqueous solution . The critical micelle concentration (CMC) of the gemini surfactant at different temperatures and mixed micelle properties of ZGS12 and sodium dodecyl benzene sulfonate (SDBS) were investigated. The results show that cmc of the gemini surfactant (ZGS12) decreases with raising temperature, Gibbs free energy changes and entropy changes are negative and postive, respectively, indicating the formation of micelle is spontaneous and driven mainly by entropy. According to the theory of regular solution , interaction parameters between the zwitterionic gemini surfactant ZGS12 and the anionic surfactant SDBS indicate strong attractive interaction and great degree of synergism in micelle formation due to weakening of the electrostatic head group repulsion.

Abstract Background Predatory flagellates and ciliates are two common bio-contaminants which frequently cause biomass losses in Chlorella mass culture. Efficient and targeted ways are required to control these contaminations in Chlorella mass cultivation aiming for biofuel production especially. Results Five surfactants were tested for its ability to control bio-contaminations in Chlorella culture. All five surfactants were able to eliminate the contaminants at a proper concentration. Particularly the minimal effective concentrations of sodium dodecyl benzene sulfonate (SDBS) to completely eliminate Poterioochromonas sp. and Hemiurosomoida sp. were 8 and 10 mg L−1, respectively, yet the photosynthesis and viability of Chlorella was not significantly affected. These results were further validated in Chlorella mass cultures in 5, 20, and 200 m2 raceway ponds. Conclusions A chemical method using 10 mg L−1 SDBS as pesticide to control predatory flagellate or ciliate contamination in Chlorella mass culture was proposed. The method helps for a sustained microalgae biomass production and utilization, especially for biofuel production.
