Abstract

The extraction of sodium dodecyl sulfate with methylene blue by polyurethane foam in the presence and absence of non-ionic surfactant additives was investigated using diffuse reflectance spectrophotometry method. The sorption-photometric method for determining sodium dodecyl sulfate in water of various types was developed. The linearity of calibration curve with the test sample volume being 25 cm3 was kept within the range of 0.04–6.0 mg/dm3.
