METHOD FOR SIMULTANEOUSLY TESTING HUMIC ACIDS AND PHENOLE IN WATER SOURCES

摘要

the invention refers to a method for simultaneous determination of humic acids and fenolului sources of water.through the analysis spectrofometrica uv absorption spectrum is recorded in water processing, without prior processing of the sample absorption maxima, ascertain 210 and 270 nm,which indicate the presence of humic acids and fenolului separately prepare a solution of 53 mg / l phenol in distilled water, in which, on dilution in volume 1: 1, 1: 2, 1: 3, 1: 4: 4 and 5,the measured extenctiile at landa = 270 nm, a solution of 5 mg / 100 humic acids in distilled water, in which, on dilution, get solutions containing 1, 2, 3 and 4 mg / 100 humic acid.the measured extinctiile at 240 nm, treat both calibration for the two substancesthe contents of humic acids from causing direct water analysed on the etalonarii at landa = 240 nm, the concentration of phenol in water on the basis of analyzing etalonarii at landa = 270 nm,given aditivitatea humic acids and fenolului absorption at this wavelength.
