Pb(II) and Cd(II) biosorption on Chondracanthus chamissoi (a red alga)
(Elsevier, 2011)
Chondracanthus chamissoi is an efficient biosorbent for Pb(II) and Cd(II). The sorption efficiency increases with pH and reaches an optimum around pH 4. Maximum sorption capacity reaches 1.37mmolPbg-1 and 0.76mmolCdg-1. ...

Selection of TiO2-support: UV-transparent alternatives and long-term use limitations for H2S removal
(Elsevier Science, 2007-11)
Supported-TiO2 is commonly used for the photocatalytic treatment of gas streams. Nevertheless, selection of the best support is not a trivialtask. Cheap, lightweight and easily shaped polymeric materials which are transparent ...
Effect of operating conditions in removal of arsenic from water by nanofiltration membrane
(Elsevier Science, 2005-02-10)
The removal of arsenic from synthetic waters and surface water by nanofiltration (NF) membrane was investigated. In synthetic solutions, arsenic rejection experiments included variation of arsenic retentate concentration, ...
Enhancement of copper toxicity in cultures of Dictyosphaerium pulchellum (Chlorophyceae) by mucilage removal
(Schweizerbart Science Publishers, 2005-04)
Extracellular mucilage from cells of Dictyosphaerium pulchellum Wood 1872 was removed by controlled ultrasonication. Batches of exponentially growing cells, with and without mucilaginous capsules, were incubated during 48 ...
Experimental investigation on arsenic removal with a nanofiltration pilot plant from naturally contaminated groundwater
(Elsevier Science, 2011-07-20)
In this research, the efficiency and the arsenic removal mechanism with a Nanofiltration (NF) pilot plant from naturally contaminated groundwater have been evaluated. The process integral evaluation at 7bar shows an arsenate ...
