Role of modified humic acids from peat in the detoxification of tebuconazole

The acid-base properties of the initial and modified humic acids from high-moor peat were studied. It was found that the acid properties of humic acid preparations increased for C n COOH groups and weakened for ArCOOH groups upon the mechanical activation of peat. The energies of dissociation and th...

Description
Summary:The acid-base properties of the initial and modified humic acids from high-moor peat were studied. It was found that the acid properties of humic acid preparations increased for C n COOH groups and weakened for ArCOOH groups upon the mechanical activation of peat. The energies of dissociation and the degrees of dissociation of ionogenic acid groups were calculated. The detoxifying properties of the modified humic acid preparations toward the fungicide tebuconazole were studied.
