Sorption kinetics and intrapaticulate diffusivity of As(III) bioremediation from aqueous solution, using modified and unmodified coconut fiber

Arsenic removal using hydrous nanostructure iron(III)–titanium(IV) binary mixed oxide from aqueous solution

“…Thus, the results (Table 3), in general, has suggested that the sorption reactions of either the As(III) or the As(V) with NHITO at the studied reaction conditions are taken place with the boundary-layer (film) diffusion. The results reported herein is similar to the results that published by Lgwe and Abia [42] on the sorption of As(III) by the modified and unmodified coconut fiber. Fig.…”

Removal of heavy metals and cyanide from gold mine wastewater

“…They found that the uptake of metal ions increased at higher temperature. Igwe and Abia133 noted that temperature and particle size are very crucial parameters in biosorption reactions. They investigated the effects of these two parameters on the biosorption of As(III) from aqueous solution using modified and unmodified coconut fibers and found that the most suitable temperature was 30 °C.…”

Sorption models of Cadmium (11) ion onto edible fruit wastes

“…It is one of priority pollutants (1,2).Cadmium is one of the inorganic contaminants of public health interest due to its high toxicity after accumulation in the organs of the human body and aquatic lives (3,4).Cadmium in its ionic form as Cadmium (11) ion is present in low concentrations in several parts of the ecosystem namely ;human organs . human cells , animal cells , aquatic lives, sediments of underground water, and in surface water The maximum permissible of Cadmium (11) ion in the natural waters is about 0.005 ppm (5).Cadmium (11) ion is chemically similar to Zinc (11) ion readily assimilated into the food chain (5,3).Sources of Cadmium (11) ion are; batteries , alloys, pigments, plastics, cigarettes, contaminated irrigated water (6,7,8).There is the need to develop a new method for the removal of Cadmium (11) ion from aqueous environment.…”
