Cr(VI) adsorption and reduction by humic acid coated on

Easily separable humic acid coated magnetite (HA-Fe3O4) nanoparticles are employed for effective adsorption and reduction of toxic Cr(VI) to nontoxic Cr(III). The adsorption and reduction of Cr(VI) is effective under acidic, neutral, and basic pH conditions. The chromium adsorption nicely fits the Langmuir isotherm model, and the removal of Cr(VI) from aqueous media by HA-Fe3O4 particles follows

Humic acid coated Fe3O4 magnetic nanoparticles as highly

15/06/2011 Humic acid coated Fe 3 O 4 magnetic nanoparticles (Fe 3 O 4 /HA) were prepared for the removal of sulfathiazole from aqueous media. Fe 3 O 4 /HA exhibited high activity to produce hydroxyl (OH) radicals through catalytic decomposition of H 2 O 2. The degradation of sulfathiazole was strongly temperature-dependent and favored in acidic solution. The catalytic rate was increased with Fe

Antimycotic nail polish based on humic acid‐coated silver

The objective of this work was the development of silver nanoparticles (AgNPs) coated with humic acid (HA) and their incorporation into an enamel for antifungal activity. AgNPs were synthesized by chemical reduction using sodium borohydride as a reducing agent and coated with HA. Uncoated AgNPs were synthesized as control. AgNPs and HA‐AgNPs were characterized by ultraviolet–visible

Adsorption of MCPA on goethite and humic acid-coated

Less pesticide was adsorbed on the humic acid-coated goethite than on the bare goethite and the pattern fitted an L-type isotherm, which indicates a change in the mechanism of adsorption. Simplified calculations with the CD-MUSIC model enabled interpretation of the results, which suggested that the pesticide molecules form the same type of

A Large-Scale 3D Study on Transport of Humic Acid

Humic acid-coated goethite nanoparticles (HA-GoeNPs) have been recently proposed as an effective reagent for the in situ nanoremediation of contaminated aquifers. However, the effective dosage of these particles has been studied only at laboratory scale to date. This study investigates the possibility of using HA-GoeNPs in remediation of real field sites by mimicking the injection and

As(V) Adsorption Kinetics of Humic Acid-Coated

In this research, magnetite (Fe 3 O 4) particles coated with humic acid were investigated for its efficacy in adsorbing As. The particles were synthesised by varying the temperature (70, 80 and 90°C) and concentration of humic acid (1%, 2% and 3%) to study the corresponding changes in terms of size, structure and As adsorption performance. The phase and size were characterised with X-ray
