Fate of linear alkylbenzene sulfonate in agricultural soil columns during inflow of surfactant pulses
The transport and reaction processes of linear alkylbenzene sulfonate (LAS) were characterised in columns of agricultural soil with a constant inflow of irrigation water. A pulse input of commercial LAS was performed with different mixtures of soil and sea sand (0/100%, 25/75% and 50/50%) and a cont...

The transport and reaction processes of linear alkylbenzene sulfonate (LAS) were characterised in columns of agricultural soil with a constant inflow of irrigation water.

LAS homologue retention was favoured at a higher soil rate, due mainly to higher clay and organic matter contents. C10LAS and C11LAS were less retained in soil columns, and were eluted faster and in higher proportion through soil columns than other homologues.
