LAS (Linear Alkylbenzene Sulphonate) shows relatively high aquatic toxicity in hard freshwater or seawater. In this paper, we studied the effect of adsorbent on the aquatic toxicity of LAS in hard freshwater and seawater. Daphnia magna and Artemia salina were used for acute aquatic toxicity test in freshwater and seawater, respectively. Kaolin was used as a model adsorbent and toxic surface ten...

Ž .Linear alkylbenzene sulphonates LAS are a group of anionic surfactants, characterised by having both ahydrophobic and a hydrophilic group. LAS is one of the major ingredients of synthetic detergents and surfactants andis used world-wide for both domestic and industrial applications. LAS is relatively rapidly aerobically degraded, butonly very slowly or not at all degraded und...

The magnetic multiwalled carbon nanotubes (MMWCNTs) have been successfully prepared using a one-pot chemical coprecipitation method, in which magnetic nanoparticles (MNPs) were deposited onto multiwalled carbon nanotubes (MWCNTs) by in situ high temperature decomposition of the magnetic precursor of iron(III) in ethylene glycol media. A novel procedure for extraction of linear alkylbenzene sulf...
