Distinct Effects of Humic Acid on Transport and Retention .

The distinct effects of humic acid (HA, 0–10 mg L–1) on the transport of titanium dioxide (rutile) nanoparticles (nTiO2) through saturated sand columns were observed under conditions of environmental relevance (ionic strength 3–200 mM NaCl, pH 5.7 and 9.0). Specifically, the transport of nTiO2 was dramatically enhanced in the presence of HA at pH 5.7, even at a low HA concentration of 1 ...
