摘要 A simple and rapid method for the determination of polyethylene oxide-type non-ionic surfactants is reported herein. This method is based on the adhesion of calcium/non-ionic surfactant complexes with tetra phenyl porphine sulfonic acid (TPPS) to the wall of reaction vessel upon vigorous shaking. The ion-associate adhering to the inner wall of the vessel was dissolved with water after discarding the solution and spectrophotometrically assayed at 412 nm. From the standard curve for Triton X-100, the order of the sensitivity for different ions was as follows: Ca^2+〉 K^+〉 NH4^+〉 Ba^2+. The proposed method does not involve extraction of the ion-associated with harmful solvents and can be simply performed by combining a procedure based on hand shaking and the use of a spectrophotometer.
