Özet:

 


Humic acids
are a principal component of humic substances, which are the major constituents
of soil (humas), peat and coal. It is a complex mixture of many different acids
containing carboxyl and phenolate groups so that the mixture behaves
functionally as a dibasic acid or, occasionally, as a tribasic acid.

Humic acid (HA) was tested in the aqueous medium to
remove hexavalent chromium Cr(VI) during this study. The extent of adsorption
of Cr(VI) on the surface of HA was examined on the basis of increasing quantity
of humic acid. An ionic interference study was also performed in order to check
the effect of various ionic salts on the adsorption process. Various salts of
calcium chloride (CaCl2), potassium chloride (KCl) and sodium
chloride (NaCl) were tested on the adsorption of Cr(VI) while using humic acid
as an adsorbent. Interactions between HA and Cr(VI) were confirmed by using
Fourier transform infrared (FTIR) spectroscopy. Further characterization was
also performed using UV-Visible spectroscopy and Scanning Electron Microscopy
(SEM) analysis.
