SDBS against hyamine

A typical photometric titration of SDBS against hyamine at low salinity is shown in Figure 3. It was noted, however, that the titration curve was "V" shaped and not the anticipated step curve. The turbidimetric titration of SDBS against hyamine afforded a curve, Figure 4, very similar to that for the photometric titration.

A detailed study of the determination of the anionic surfactant SDBS by automated titration against hyamine using an autotitrator has been undertaken. The following conclusions and observations can be made.
