RAMIREZ T., Gustavo. APLICACIÓN DE LA ESPECTROFOTOMETRÍA ULTRAVIOLETA PARA DETERMINAR EL OXÍGENO DISUELTO EN AGUA POR EL MÉTODO WINKLER. Bol. Invest. Mar. Cost. [online]. 1992, vol.21, n.1, pp.95-100. ISSN 0122-9761.

Ultraviolet spectrophotometry as an alternative technique to the thiosulphate titration for the dissolved oxygen evaluation of natural waters by Winkler method was used. Analysis of waters with different salinities (Río Manzanares, Ciénaga Grande, Bahía de Santa Marta) did not show statistically significant differences (p<0.05) between titration and photometry measurements, which suggest this technical modification can be applied in freshwater and marine aquatic systems.
