| Abstract: | A method for the spectrophotometric determination of glutaraldehyde based on the reaction of glutardehyde and thiobarbituric acid in acetic acid solution is described. The absorbance was measured at 453 um. The linear range of the calibration curve is in 0. 5 - 10. 0 mg/L. The detection limit of glutaraldehyde is 0. 019 mg/L. The method was proved to be simple, rapid and accurate. It has been used for the determination of glutaraldehyde in some sterilizing solutions successfully. |
