The effect of pH on the binding of heavy metal ions with humic substances and hymatomelanic acids of peats

The values of the dissociation constants (–COOH and –OH) of humic substances and hymatomelanic acids have been determined by the potentiometric titration method. It has been shown that hymatomelanic acids are enriched in phenolic groups compared with the original humic substances. The solubility of...
