| Abstract: | It is reported in this paper that a spectrophotometric determination of iodide as an ion associate of CTMA~+I_3~- after solvent floatation in an atomosphere of carbon dioxide and using cetyl trimethyl ammonium bromide as collector is proposed. The method has high sensitivity and good accuracy and precision. |
