Влияние гуминовых кислот на наночастицы ZnO

Abstract

The effect of natural organic matter, as humic acids, on the colloidal and thereby, biological, properties of nanoparticles is of great importance. Therefore, in this work we examined aggregative properties of ZnO nanoparticles with average size of 40 nm in differently concentrated solution of humic acids. Using the spectrophotometry method, it has been shown that the sedimentation rate of ZnO nanoparticles decreases in three times compared to distilled water. It has been found that with an increase in humic acids content from 10-10 to 10-4 mgL-1, the sedimentation rate of the particles increases.
