Abstract :
A simple, low-cost and sensitive method has been used to investigate the
interaction between a cationic surfactant, tetradecyltrimethylammonium bromide (TTAB),
two anionic dyes, C.I. Direct Orange 26 (DO26) and C.I. Direct Red 16 (DR16), and a drug,
Atenolol (ATN). The methods used to study the interaction were electromotive force (EMF)
measurements involving a surfactant–selective electrode and spectrophotometry. This method
was also used to investigate the interactions of Atenolol (ATN). The interaction between
TTAB and DO26 was found to be stronger than that of TTAB and DR16. TTAB only showed
a weak interaction with ATN at a high drug concentration. Therefore, when ATN was added
to a mixture of TTAB and the dye, ATN was found to first interact with the dye and, when
ATN saturated, a higher concentration of TTAB interacted with the dye.
