Semakin banyak jenis limbah yang masuk dalam perairan mengakibatkan pencemaran. Pencemaran lingkungan berasal dari senyawa organik dan anorganik, sehingga perlu dilakukan pengolahan air limbah. Salah satu cara untuk mengatasi pencemaran terdapat di dengan teknik fitoremediasi. Tujuan penelitian ini mengetahui konsentrasi LAS pada tercemar agen fitoremidiasi tanaman jeruju (Acanthus ilicifolius)...

The anionic surfactant linear alkylbenzene sulfonate (LAS) may inhibit soil microorganisms and may occur in agricultural soil through the application of sewage sludge. For five microbial parameters (microbial biomass C and the potentials of iron reduction, ammonium oxidation, dehydrogenase activity, and arylsulfatase activity), we compared the effects of aqueous LAS and LAS-spiked sewage sludge...

Linear alkylbenzene sulfonate (LAS) is widely used in the formulation of domestic and industrial cleaning products, the most synthetic surfactants used worldwide. These products can reach water bodies through the discharge of untreated sewage or non-effective treatments. This study evaluates the ability of the microorganisms found in the Tiete river sediment to degrade this synthetic surfactant...

Introduction: Detergents lead to many environmental problems. The main aim of this study was to evaluate sequencing batch reactor (SBR) efficiency on Linear alkyl benzene sulfonate (LAS) removal. Materials and Methods: In this experimental study, to investigate the removal efficiency of LAS, a SBR reactor was used. A roughly 12-hour operating cycle was chosen which included the discharge time ...

Knowledge on interactive effects of global (e.g. ocean warming) and local stressors (e.g. pollution) is needed to develop appropriate management strategies for coral reefs. Surfactants and diesel are common coastal pollutants, but knowledge of their effects on hard corals as key reef ecosystem engineers is scarce. This study thus investigated the physiological reaction of Pocillopora verrucosa ...

Laboratory column experiments were conducted to study the effects of anionic polyacrylamide (PAM) polymer and surfactant linear alkylbenzene sulfonate (LAS) on the movement of Escherichia coli and the FRNA phage MS-2. The study was designed to evaluate if PAM or PAM + LAS would enhance the mobility of human pathogens in tropical soils under unsaturated conditions. No breakthrough of phage was o...

A flow immunoassay based on a combined technique of the sequential injection with the beads injection using magnetic microbeads immobilized with antigen or antibody is described. A methodology of the present immunoassay based on chemiluminescence and electrochemical detection and its application to the determination of vitelloginin (Vg) and anionic surfactant, linear alkylbenzene sulfonate (LAS...

In this study, the results of application advanced oxidative processes to remove linear alkylbenzene sulfonate (LAS) from wastewater produced in laundry industry are presented. Photocatalysis with UV radiation and oxygen peroxide (H2O2) was applied followed by ozonation (O3). LAS removal higher than 90% first 60 min. H2O2 based on COD reached its most effective concentration for rate [1:2.5] O3...
