Fluorescence analysis of humic and fulvic acids from two Brazilian oxisols as affected by biosolid amendment.

Abstract

Conventional monodimensional fluorescence spectroscopy in the emission, excitation, and synchronous-scan modes and total luminescence spectroscopy have proven to be sensitive techniques for characterization and differentiation of humic acid (HA) and fulvic acid (FA) fractions isolated from an aerobically and anaerobically digested and limed biosolid, two… (More)
