A colloid titration method for the determination of sodium dodecylbenzenesulfonate (LAS) with poly(4-vinyl-1-pentylpyridinium bromide) (polysoap) is described. The end-point detection is based on the measurement of turbidity, the transmittance at 420 nm or 680 nm being used for the determination. The most successful results were obtained by titrating LAS (1–7.5×10<SUP>−4</SUP> N) with 2.5×10<SUP>−3</SUP> N polysoap solution. The purity of commercial LAS was found to be 81–84%.
