Determination of Sodium Linear Alkylbenzenesulfonate in River Water Containing Household Wastewater

摘要

The effects of concomitant substances on colorimetric determination of sodium linear alkylbenzenesulfonate using Methylene Blue were studied with respect to proteins, food oil and starch, all considered to be components of household effluents. The determined values were compared with those obtained by high-performance liquid chromatography (HPLC). The quantitatively determined values were found to induce a negative error in the presence of proteins. This negative error was eliminated by the addition of propyl alcohol.
