Detata-Filters for Metal Preconcentration and Multielement Determination in Natural Waters

Abstract New sorption filters containing conformationally flexible aminc-carboxylic groups were proposed for preconcentration of metals. Quantitative recovery of metals was achieved in a dynamic

Extracting Minerals from Seawater: An Energy Analysis

The concept of recovering minerals from seawater has been proposed as a way of counteracting the gradual depletion of conventional mineral ores. Seawater contains large amounts of dissolved ions and

Recovery of Uranium from Seawater: A Review of Current Status and Future Research Needs

The recovery of uranium (U) from seawater has been investigated for over six decades in efforts to secure uranium sources for future energy production. The majority of the research activities have

Mining the Oceans : Can We Extract Minerals from Seawater ?

  • Geology
  • 2009
After a couple of centuries of mining, the best and most concentrated mineral ores are on their way to disappearance. In the future, we'll have to extract from less concentrated deposits and that

Selective Rejection of Dissolved Uranium Carbonate from Seawater Using Cross-Flow Filtration Technology

Abstract: Cross-flow membrane filtration equipment was operated to evaluate the selective uranium carbonate rejection from seawater of different flat sheet membranes. The membranes were

Seawater uranium sorbents: preparation from a mesoporous copolymer initiator by atom-transfer radical polymerization.

N nanoporous polymers based on the vinylbenzyl chloride (VBC) monomer and the DVB cross-linking agent are reported, which are the first examples of ATRP initiators in which the initiator species is located within the framework of the mesoporous support.

Macroporous monoliths for trace metal extraction from seawater

The viability of seawater-based uranium recovery depends on the uranium adsorption rate and capacity, since the concentration of uranium in the oceans is relatively low (3.3 μg L−1). An important

Selective recognition and extraction of the uranyl ion from aqueous solutions with a recyclable chelating resin

An ion exchange polymer 1, incorporating a chelating ligand engineered for the uranyl ion was prepared and its ability to remove uranium from aqueous solutions was studied. The chelating module was



On the Extraction of Uranium from Sea Water by a Complexing Resin

Abstract A cross-linked polyacryl resin containing amidoxime or related functional groups is capable of concentrating uranium from natural sea water. The resin presents a uranium loading of more than

Separation of trace-metal ions from seawater by adsorptive colloid flotation

An adsorptive colloid flotation process based on a collector–surfactant–air system makes possible the rapid separation of various cationic and anionic metallic species from seawater.

Determination of Silver in Sea Water after Flotation with 2-Mercaptobenzothiazole

Nanogram quantities of silver in 3000 ml of acidified sea water were quantitatively coprecipitated with 2-mercaptobenzothiazole. The precipitate was then floated with the aid of small nitrogen
