Removal of fluoride from drinking water by adsorption onto alum-impregnated activated alumina
The ability of the alum-impregnated activated alumina (AIAA) for removal of fluoride from water through adsorption has been investigated in the present study. All the experiments are carried out byExpand
Abatement of fluoride from water using manganese dioxide-coated activated alumina.
The mechanism of fluoride uptake by MCAA is due to physical adsorption as well as through intraparticle diffusion which was confirmed by kinetics, Dubinin-Raduskevich isotherm, zeta-potential measurements and mapping studies of energy-dispersive analysis of X-ray. Expand
Chlorination byproducts, their toxicodynamics and removal from drinking water.
In order to reduce the public health risk from these toxic compounds regulation must be inforced for the implementation of guideline values to lower the allowable concentrations or exposure. Expand
Enhanced adsorption capacity of activated alumina by impregnation with alum for removal of As(V) from water
Alum-impregnated activated alumina (AIAA) was investigated in the present work as an adsorbent for the removal of As(V) from water by batch mode. Adsorption study at different pH values shows thatExpand
A process for the selective removal of arsenic from contaminated water using acetate functionalized zinc oxide nanomaterials
This research article deals with the uptake of arsenic from contaminated water using acetate functionalized zinc oxide (ZnO) nanomaterials. The ZnO nanomaterials of various sizes (6–60 nm) have beenExpand
Adsorption of Co2+, Ni2+, Cu2+, and Zn2+ onto amorphous hydrous manganese dioxide from simple (1-1) electrolyte solutions.
The adsorption of Co2+, Ni2+, Cu2+, and Zn2+ onto amorphous hydrous manganese dioxide (delta-MnO2) has been studied using two methods, viz., isotherms at constant pH in the presence of bufferExpand
The Electrical Double Layer at Hydrous Manganese Dioxide/Electrolyte Interface.
The interfacial properties of two hydrous oxides of manganese, namely an amorphous variety and a poorly crystalline synthetic birnessite, in different electrolyte media, have been studied by using a batch potentiometric titration procedure with a 72-h equilibration period and it is concluded that the triple-layer model is not applicable to this colloid system.

Dispersion studies of sub-micron zirconia using Dolapix CE 64
In this paper, the effect of a commercial carbonic acid based polyelectrolyte, Dolapix CE 64, on stabilization of sub-micron size zirconia suspension is reported. The effect of pH, concentration ofExpand
Adsorption of Co2+, Ni2+, Cu2+ and Zn2+ from 0.5 M NaCl and major ion sea water on a mixture of delta-MnO2 and amorphous FeOOH.
The pH(pzc) values of several mechanical mixtures of amorphous hydrous oxides of iron (amorphous FeOOH) and manganese (delta-MnO2) have been determined using the solid addition method and it is generally observed that the adsorption on the mixed oxide system is higher than that on delta-MmO2 alone under similar condition.

Adsorption of Cd2+ on hydrous manganese dioxide from aqueous solutions
The adsorption of Cd2+ onto amorphous hydrous manganese dioxide (δ-MnO2) has been studied in (a) 0.5 M NaCl solution and (b) major ion seawater. The adsorption experiments were carried out in twoExpand
