Abstract
Complexation between silver (Ag+) and p-iodobenzenediazoaminoazobenzene (p- IBDA) has been investigated in alkaline solution. The surfactants, polyoxye thylene alcohol (OP) and sodium dodecyl benzene sulfonate (SDBS) have been used because their micelles can improve the dissolution of the Ag-p-IBDA co mplex and increase the reaction sensitivity. Its true (not apparent) molar absorptivity is epsilon (480)(Ag(p-IBDA)) = 3.42 x 10(4) in OP solution and epsilon (490)(Ag(p-IBDA)) = 2.59 x 10(4) dm(3) mol(-1) cm(-1) in SDBS solu tion. The stability constants of the complex are 1.63 x 10(7) and 5.16 x 10 (4) in OP and SDBS solutions, respectively.
