Correlations for estimation of acid equivalents of regenerated humic acid
The purpose of the present investigation is to establish a relation between acid equivalents and the atomic [O]/[C] ratio of regenerated humic acids. A linear relationship is found to exist between acid equivalents and atomic [O]/[C] ratio of regenerated humic acids. Correlation coefficients for equations relating acid equivalent produced by various methods (namely titration, ion-exchange and formulation of copper salt) with the atomic [O]/[C] ratio ranged between 0.91–1.00 on a dry-ash-free basis and 0.94–0.97 on a dry-mineral matter-free basis.
