| Abstract | ||
| Indirect spectrophotometric method has been described for determination of microgram amounts of acetaniiide in aqueous solution. The method based on the acid hydrolysis of acetaniiide and the produced aniline is reacted with DDQ reagent as 7t-acceptor at pH 9 to form charge transfer complex with maximum absorbance of 345 nm. Beer's law obeyed the concentration range of 0.1-4.0 ug / ml of acetaniiide and the molar absorptivity is 13600 1/mol.cm with good precision and accuracy, also, the optimum conditions of the reaction are studied.0 | ||
