HUMIC ACID EXTRACTION FROM WEATHERED COAL AND ITS SPECTROSCOPIC RESEARCH
摘要
Abstract
Extraction of brown humic acid and black humic acid from weathered coal was briefly introduced here. Two kinds of humic acid extracted were characterized respectively by ultra violet-visible spectra, Fourier transformed infrared spectra and three-dimensional fluorescence spectra and the structural differences of them were also illustrated. The structure of functional groups in them was similar but the content of functional groups in brown humic acid was higher than black humic acid overall which was gotten by Fourier transformed infrared spectra. The ab-sorbance ultra violet-visible spectra of both humic acids in the spectroscopy region was decreased with wavelength increasing, which was a mixed spectrum. Both kinds of humic acid had fluorescent effect and the redshifts would happen no matter with concentration increasing or pH value increasing.关键词
