Characterization of Metal Ion Complexes with Humic Fractions of Farmyard Manure by Potentiometric Titrations (original) (raw)
International Journal of Current Microbiology and Applied Sciences
AI-generated Abstract
This study investigates the characterization of metal ion complexes with humic fractions present in farmyard manure through potentiometric titrations. The research found that as the pH of humic and fulvic acids increased during titration, it indicated a higher buffering capacity. Notably, the titration curves suggested that stable complexes were formed with various metal ions, particularly highlighting that zinc demonstrated increased complex stability at higher pH levels. These findings suggest potential applications of humic fractions as effective carriers of micronutrients in crop nutrition, reducing nutrient loss via leaching.
