1/11/2010· In this work, removal and recovery of phosphorus from treated wastewater by High Gradient Magnetic Separation (HGMS) with ferromagnetic zirconium ferrite adsorbent were studied. Phosphorus in the treated wastewater could be removed from 1.12 mg/L to 0.03 mg/L by the HGMS system with 500 mg/L zirconium ferrite adsorbent for 5 min in adsorption time. The magnetic separation speed
High-performance liquid chromatography (HPLC; formerly referred to as high-pressure liquid chromatography) is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material.
Use of the bacitracin-linked magnetic supports for a single cycle of batch adsorption and subsequent capture by high gradient magnetic separation at a processing rate of 12 m h −1 resulted in a 2.2-fold higher productivity relative to expanded bed adsorption, while an increase in adsorbent collection rate to 72 m h −1 raised the
‘Liquid is drawn off to a high gradient magnetic separator where the non-magnetic fraction containing decontaminated liquid is separated off; the slurry is removed for use as an adsorbent.’ ‘An effort was made to utilize a low cost adsorbent for retaining metal ions from leaching out into water resources.’
20/08/2017· Magnetite-zeolite composites (MZCs) and an MZC modified with poly(N-isopropylacrylamide) (PNIPAM) (PMZ) were prepared in this study as adsorbents for Cs + ions.The ratios of the removal of these magnetic adsorbents from suspensions using high-gradient magnetic separation (HGMS) were examined.
Adsorption capacity (or loading) is the amount of adsorbate taken up by the adsorbent per unit mass (or volume) of the adsorbent. 1 The adsorption capacity of a solid desiccant for water is expressed as the mass of water adsorbed per mass of desiccant. There are three water-adsorption capacity terms used as follows (Campbell, 2000):Static equilibrium capacity: the water capacity of a new

By a 10 tesla superconducting high-gradient magnetic separator, 10 ppb uranium ions in sample solution could be reduced to less than 1 ppb level successfully with the 100 ppm adsorbent addition. Adsorption time dependence for the uranium ions at pH = 7 shows that the effective adsorption sites are located on the particle surface. A different
