Towards synergistic combination of biochar/ultrasonic persulfate enhancing removal of natural humic acids from water
Popis výsledku v původním jazyce
Removal of natural organic matter (NOMs) from actual water is a major challenge in the context of worldwide pollution of natural water resources. The removal of humic acids in a system combining biochar adsorption and ultrasonic persulfate oxidation was studied in this paper. The effects of biochar addition, persulfate concentration and initial pH were investigated. A high removal rate of humic acids up to 92,5% was achieved for the combined biochar/ultrasonic/persulfate system, versus 84,0% for combined biochar/persulfate, 52,0% for sole biochar, 50,0% for combined biochar/ultrasonic, 10,0% for combined persulfate/ultrasonic, 4,0% for sole ultrasonic and 1,0% for sole persulfate systems. Ultrasonic treatment increased the removal efficiency of humic acids to 90,0% within 60 min. Mechanisms towards synergistic combination of the biochar/ultrasonic/persulfate system were investigated by gel permeation chromatography, electron paramagnetic resonance and quenching experiments together with the character
