In this reference for scientists, international contributors describe technologies and techniques for removing organic and inorganic contaminants from water, with special attention paid to remediation of arsenic contamination, as well as remediation methods for various water contaminants including ferrates
, copper, slag, nitrates, hydroxyl radical, and ozone.
The addition of soda and calcium oxide convert iron, silica and titania impurities into insoluble sodium and calcium ferrates, silicates as well as sodium titanate.
The equivalent weight percents of alkaline compounds (CaO and Na2CO3) were blended with 150 g bauxite by Siebtechnik grinding machine in order to form aluminate, silicate, ferrate and titanate (Table-1).
The high point of our holiday, quite literally, was a day spent on the Vies Ferrates - the 'iron ways' - near the village of Ordino.
Anyone who thinks that if they can climb a ladder they can climb a via ferrate will be seriously disabused of this notion within minutes of setting out.
Climbers wear a harness with two safety ropes, which must be attached to the cable that runs alongside their vie ferrate of choice.
GOING UP: The Vie Ferrate is not for the faint hearted.
The ferrate crystal belongs to orthogonal crystal system.
Iron (VI) ions in potassium ferrate, located in the highest valence state of iron, have strong oxidativity; also they have selectivity.
Heavy metal pollutants in the micropolluted water, such as cadmium and manganese, can be removed by potassium ferrate, and the removal rate reached 80%.
This paper completes the transformation and removal of aromatic hydrocarbons in micropolluted water, in view of the refractory aromatic hydrocarbon in micropolluted source water and in view of potassium ferrate treatment technology.
The infrared spectrum of potassium ferrate by Fourier infrared spectrometer (FTIR) is drawn, and the infrared characteristic peaks of potassium ferrate crystal are measured.
