A comparative study of the adsorption of linear alkylbenzene sulfonates and their biodegradation intermediates on marine sediments and organisms

A comparative study of the adsorption of linear alkylbenzene sulfonates and their biodegradation intermediates on marine sediments and organisms

Linear alkylbenzene sulfonate (LAS) and sulfophenylcarboxylate acid (SPC) adsorption on suspended material (sediment and phytoplankton) has been determined in laboratory experiments. The kinetic characterization of the adsorption process allows the time to the steady state to be established, which w...

La adsorción de alquilbenceno lineal sulfonatos (LAS) y ácidos sulfofenilcarboxílicos (SPC) sobre material en suspensión (sedimento y fitoplancton) ha sido determinada en experimentos de laboratorio. La caracterización cinética del proceso de adsorción permite establecer el tiempo para alcanzar el estado estacionario, el cual fue de 12 y 18 horas, para LAS y SPC, respectivamente. Los coeficientes de adsorción normalizados al contenido en carbono orgánico para sedimentos y el contenido lipídico para microalgas, son similares para cada compuesto, mostrando una clara relación con el carácter no polar del mismo. Así, los mayores coeficientes observados corresponden a los LAS (8 × 103). Se ha observado también una cierta dependencia con la especie de alga. Así, Nannochloropsis gaditana presenta coeficientes de adsorción mayores, tanto para LAS como para SPC, que Dunaliella salina.
