Sorption-photometric determination of sodium dodecylsulfate with methylene blue on polyurethane preliminary treated by organic solvent

Resumo

The paper has investigated the possibility of using preliminary treatment of polyurethane tablets by organic solvents for determination of anionic SAS. A technique has been developed of their sorption-photometric determination in waters with a detection limit 0.004–0.144 mg/dm³ depending on the wave length.
