Probing the interaction effects of metal ions in Mn FeO on arsenite oxidation and adsorption.

Wastewater treatment is still a global concern and materials capable of pollutant sequestration continue to be improved in a bid to ensure water reusability and curb water shortages. Some of the most promising materials so far are nanosized materials because of their unique properties and the ease of manipulation to improve their properties. In this work we investigated the effects of varying Fe : Fe ratios in magnetite nanoparticles and the influence of manganese doping.

New species in the sponge genus (Poecilosclerida, Latrunculiidae) from South Africa.

The genus Samaai & Kelly, 2002 is to date exclusively reported from South Africa. Three species are known from the southern coast: Samaai & Kelly, 2002, from the Garden Route National Park Tsitsikamma Marine Protected Area (MPA) and Algoa Bay; Samaai, Gibbons, Kelly and Davies-Coleman, 2003, collected from Cape Recife in St. Francis Bay, and Samaai, Gibbons, Kelly and Davies-Coleman, 2003, collected from a wreck site in a small bay west of Hout Bay on the west coast of South Africa.
