Surface active agents - Sodium dodecyl sulfate - Analytical method

This European Standard specifies a method for the determination of the active content and molar mass of sodium dodecyl sulphate used as original titre for the titre determination of standard solutions for surface active agents titration.
NOTE   These are used in the mixed indicator two-phase titration (e. g. ISO 2271) and in the potentiometric titration using a surface active agent sensitive electrode (e.g. EN 14480).

Grenzflächenaktive Stoffe - Natriumdodecyulsulfat - Analysenverfahren

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Gehaltes und der mittleren molaren Masse
von Natriumdodecylsulfat, das als Urtitersubstanz für die Bestimmung des Titers von Maßlösungen für die
Titration von grenzflächenaktiven Stoffen eingesetzt wird, fest.
ANMERKUNG Die Titer werden bei der Mischindikator-Zweiphasentitration (z. B. ISO 2271) und bei der potentio-metrischen
Titration mit einer Tensid-sensitiven Elektrode benötigt (z. B. EN 14480).
