Abstract Infrared spectral studies of aqueous solution have been severely limited by the strong water absorption. Usually，it is very difficult to experimentally achieve perfect compensation between the amount of water that contributes to the sample and background spectra. In the present paper, we introduced a new method to make the infrared bands of water disappear during the measurement of an infrared spectrum for aqueous solution. Both background spectrum of the empty ATR cell and that of the water on ATR cell are used in sequence. Qualified infrared spectra of 10% K2CO3 and 10% BSA aqueous solutions were successfully obtained by ATR accessory (single-reflection) without water interference. The experimental results demonstrated that the new method is fast, effective and powerful. The limitation of the new method is also discussed.
