Combustion Synthesis Ironmaking: Investigation on Required Carbon Amount in Raw Material from the Viewpoint of Adiabatic Flame Temperature Calculation

Indonesian Journal of Chemistry, 2019
Combustion synthesis (CS) is a simple and very fast method to synthesize a target material. New ironmaking method via the CS using carbon-infiltrated iron ore was proposed, and the possible conditions for the method were investigated.

Effectiveness of Arsenic Co-Precipitation with Fe-Al Hydroxides for Treatment of Contaminated Water

Revista Brasileira de Ciência do Solo, 2018
Wastewater treatment is a challenging problem faced by the mining industry, especially when mine effluents include acid mine drainage with elevated arsenic levels. Iron (hydr)oxides are known to be effective in removal of As from wastewater, and although

Towards Building a Unified Adsorption Model for Goethite Based on Variable Crystal Face Contributions: III Carbonate Adsorption

Colloids and Interfaces
Goethite, a ubiquitous Fe(III) oxyhydroxide mineral, typically occurs in very small particle sizes whose interfacial properties critically influence the fate and transport of ionic species in natural systems.

Kinetics of phosphate sorption by goethite‐ and bentonite‐goethite (b‐g) system

Communications in Soil Science and Plant Analysis, 1998
Abstract The study of phosphate (PO4) fixation due to reactions which occur to the surface of soil minerals has been limited by a lack of evidence on which a structural model may be based. A structural model should attempt at least to describe the coordination on the absorbed PO4 3‐ ion, that is, to indenfity the immediate neighbour atoms or ions in ...

Study on the adsorption characteristics of cadmium by five soil colloids

四川大学学报. 自然科学版, 2019
Soil colloids, as the most subtle and active part of the soil, play a major role in the accumulation of heavy metals in the soil. Study on the effect of different soil colloids on the adsorption-desorption behavior and the transformation of chemical ...

Templating Iron(III) Oxides on DNA Molecules

Nanomaterials
Fe(III) oxides were prepared as free nanoparticles and on DNA templates via the precipitation of Fe(III) salts with NaOH in the presence/absence of DNA. Through control of the pH and temperature, FeOOH and Fe2O3 were synthesised.
