METHODS OF THE HIGHLY EFFECTIVE LIQUID CHROMATOGRAPHY ON IDENTIFICATION OF ALDEHYDES IN WATER

Cover Page

Abstract


The article presents environmental assessment method and high performance liquid chromatography with solid phase extraction for detection of aldehydes in water. Presents a modernized method gives a number of significant advantages: considerably time procedure reduces sample preparation, compared with traditional liquid extraction, easy to use and significantly reduces the amount of materials used and reagents in the determination of aldehydes in water. Separation of substances was achieved on reversed-phase C18 column chromatography using a mixture of deionized water and acetonitrile as the mobile phase. Determination of formaldehyde in water was performed at the absorption wavelength of 360 nm. Linearity was achieved in the concentration ranges from 1 to 200 mkg/dm3. Values of repeatability (RSD) presented the method was 15% and the total precision is 10% for control samples at all levels, including lower limit of quantification.
