Abstract
Fourier transform infrared spectroscopy has been used for the quantita tive determination of dodecylbenzenesulfonate and tripolyphosphate in solid commercial samples of detergents. The only sample treatment cons isted of a separation with ethanol. Dodecylbenzenesulfonate was dissol ved and tripolyphosphate remained in the insoluble fraction. The metho d consisted of transmission measurements of KBr pellets. Precision, re covery and determination using both calibration line and standard addi tion have been optimized. The determination of dodecylbenzenesulfonate has been compared with the UV method.
