Polyoxazoline associated with cardanol for bio‐based linear alkyl benzene surfactants

Biodegradation of Linear Alkyl Benzene Sulfonate by Sequencing Batch Reactor in Sanitary Wastewater

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 ...

Alkyl Benzene as a Compressor Lubricant

Predicted No-effect Concentrations and Risk Characterization of Four Surfactants: Linear Alkyl Benzene Sulfonate, Alcohol Ethoxylates, Alcohol Ethoxylated Sulfates, and Soap

Assessment of aquatic effects requires the derivation of a predicted no-effect concentration (PNEC). In the framework of the Dutch ‘‘Plan of Action Laundry and Cleaning Products,’’ PNECs were derived for linear alkyl benzene sulfonate (LAS), alcohol ethoxylates (AE), alcohol ethoxylated sulfates (AES), and soap. All stages in an aquatic effects assessment were used: initial (assessment factors ...

Study of Linear Alkyl Benzene (LABs) as molecular marker of sewage pollution in Bivalves Mollusk “AnodontaCygnea” in Anzali lagoon

Tracking and determining the amount and types of urban sewage that is being releasing to the environment is important in planning for wastewater treatment systems and water quality control. In this research, in four stations of Anzali Lagoon, (by means of a gas chromatograph device with mass detector spectrometer) wastewater pollution has been measured and evaluated with molecular indicator Lin...
