Abstract
A study has been made using the'H-n.m.r. spectroscopic technique to
inllestigate the structure or some humic acids extracted (rom different composts.
The results galle useful information about the nature of the extracted humic
acids, whiCh differed slightly from one to another and quite similar with a litlle
difference in the intensity of the resonances.The 'H-NMR spectra of the extracted
humic acids identified polymethylene compounds and terminal melhyl groups 01
polymethylene chains. In addition, protons attached to carbon J to carboxylic groups
or aromatic rings have also identified. 'H-NMR spectra of the studied humic acids
showed that protons of aromatic rings are presented in humic acids.
The humic acid extracted from Bostan compost (Bos-HA) contained the
highest aliphatic hydrogen content. On the other hand, humic adds from Sanbest
(San·HA) and AI-Enzy (Enz-HA) composts exhibited the highest aromatic hydrogen
content.
