Abstract
The way of definition of formaldehyde in water by the method of high performance liquid chromatography (HPLC) with the use of solid-phase extraction for concoction and extraction of the analyzed derivative formaldehyde is presented. The method is distinguished by the simplified and accelerated procedure of the sample preparation in comparison with classical liquid extraction. Chromatographic division of substances was reached on the turned phase column C18 with the use of mixture of the deionized water and an acetonitrile as a mobile phase. Definition was carried out at absorption wavelength of 360 nanometers. Linearity was reached in the ranges of concentration from 1 to 200 mcg/l. Full validation of a method is carried out. For control samples of all levels, including the lower limit of quantitative definition, the value of repeatability (RSD) accounted for ≤15%. The index of the accuracy amounted to ≤10%. The presented way showed good validation characteristics and can be recommended for the simplification and acceleration of the determination of the content of formaldehyde in water by the HPLC method
