Original Abstract

Adding the humic acid coating to the nanoparticles of zinc oxide (ZnO-NP) may improve the properties necessary for their colloidal stability. To show how humic acid coating affects the properties of ZnO-NP, three differently sol–gel synthesized ZnO-NP were synthesized: pristine zinc oxide nanoparticles without coating (p-ZnO-NP) and humic acid coated zinc oxide nanoparticles at two different initial concentrations of 20 mg/L (HA20-ZnO-NP) and 200 mg/L (HA200-ZnO-NP) of humic acids in the starting solution. All ZnO-NP were found to be nanocrystals of mineral zincite exhibiting wurtzite crystal symmetry. Transmission electron microscopy showed that capping by humic acids during synthesis decreased the size of HA20-ZnO-NP and HA200-ZnO-NP compared to p-ZnO-NP nanoparticles. Via experiments, HA20-ZnO-NP were found to dissolve less and have a similar or higher stability than both p-ZnO-NP and HA200-ZnO-NP
