Analytical applications of sodium lauryl sulphate II.—The volumetric determination of sulphates

Abstract

The literature on the ethylenediaminetetra‐acetate method for determination of sulphate is reviewed and the limitations of the method are discussed. In the procedure now described, after precipitation of sulphate as barium sulphate, excess barium is precipitated with sodium lauryl sulphate and excess of the latter titrated with a suitable quaternary ammonium salt as described in Part I of this series.
