Adsorptive properties of silica gel for biodiesel refining
(American Chemical Society, 2008-11)
The refining of biodiesel by adsorption over silica gel was assessed. Silica gel samples were used for the adsorption of glycerol and monoglycerides. Room-temperature isotherms for the adsorption of glycerol were measured ...
Adsorption of reactive dye on seawater-neutralised bauxite refinery residue
(2013-02-11)
This investigation has demonstrated the need for thermal treatment of seawater neutralised red mud (SWRM) in order to obtain reasonable adsorption of Reactive Blue dye 19 (RB 19). Thermal treatment results in a greater ...

Water vapor adsorption performance of Ag and ni modified 5A zeolite
(Elsevier, 2018-07-15)
In this work, Ag and Ni metals incorporation effect on the water adsorption and physicochemical properties of 5A zeolite was studied. For that, Ag/5A and Ni/5A zeolites with different amounts of metal (4, 10 and 20 wt%) ...
CHROMIUM ADSORPTION FROM TANNERY EFFLUENTS BY ACTIVATED CARBONS PREPARED FROM COCONUT SHELLS BY CHEMICAL ACTIVATION WITH KOH AND ZNCL2
(Sociedad Chilena de Química, 2005)
Adsorption of MX2 (M = Mn, Ni, Cu, Zn, and Cd; X = Cl, Br, and I) and FeCl3 by modified silica surface with imidazolylpropyl group
(1985-09-01)
Silica gel surface modified with imidazolylpropyl group was used to adsorb MX2 (M = Mn, Ni, Cu, Zn, and Cd; X = Cl, Br, and I) and FeCl3 from ethanol and acetone solution. The adsorption capacity and the intensity of the ...

Multilayer adsorption of Cu(II) and Cd(II) over Brazilian Orchid Tree (Pata-de-vaca) and its adsorptive properties
(Elsevier B.V., 2015-08-01)
Through very simple and inexpensive processes, pata-de-vaca leaves were turned into a powder and applied as an adsorbent for the uptake of Cu(II) and Cd(II) from water. The material was characterized through SEM, EDX, FTIR ...
Rheological properties of tin oxide suspensions
(2002-08-01)
The rheological properties of tin oxide slurries were studied experimentally and theoretically. The deflocculants used were ammonium polyacrilate (PAA) and the copolymer poly(vinyl butyral-co-vinyl alcohol-co-vinyl acetate) ...
