Abstract

Przedmiotem zgłoszenia jest sposób określania stężenia dodecylosiarczanu sodu w roztworach wodnych za pomocą testu probówkowego. Podstawę oznaczenia stanowi zjawisko tworzenia trudno rozpuszczalnego asocjatu dodecylosiarczanu sodu z barwnikiem — błękitem alcjańskim. Po przekroczeniu określonego stosunku ilościowego składników asocjat w pełni wytrąca się z roztworu, powodując całkowite odbarwienie supernatanta, co stanowi sygnał analityczny łatwy do wizualnego odczytu. Sposób polega na tym, że do probówek zawierających określoną ilość barwnika - błękitu alcjańskiego, wprowadza się rosnąco dawki analizowanego roztworu SDS, następnie powstałą mieszaninę pozostawia się do zakończenia sedymentacji osadu, kolejno wyznacza się próbkę, w której osad wytrącił się, a supernatant całkowicie odbarwił przy najmniejszej dawce analitu, po czym wylicza się stężenie analitu.
