Abstract

A preconcentration approach to assist in the measurement of low levels of americium and plutonium in waste waters has been developed based on the concept of using water-soluble metal-binding polymers in combination with ultrafiltration. The method has been optimized to give over 90% recovery and accountability from actual waste water.

Evaluation of synthetic water-soluble metal-binding polymers with ultrafiltration for selective concentration of americium and plutonium

Conference Smith, B F ; Gibson, R R ; Jarvinen, G D ; ...

Routine counting methods and ICP-MS are unable to directly measure the new US Department of Energy (DOE) regulatory level for discharge waters containing alpha-emitting radionuclides of 30 pCi/L total alpha or the 0.05 pCi/L regulatory level for Pu or Am activity required for surface waters at the Rocky Flats site by the State of Colorado. This inability indicates the need to develop rapid, reliable, and robust analytical techniques for measuring actinide metal ions, particularly americium and plutonium. Selective separation or preconcentration techniques would aid in this effort. Water-soluble metal-binding polymers in combination with ultrafiltration are shown to be an effectivemore »« less

Water-soluble metal-binding polymers with ultrafiltration: A technology for the removal, concentration, and recovery of metal ions from aqueous streams

Conference Smith, B F ; Robison, T W ; Jarvinen, G D

The use of water-soluble metal-binding polymers coupled with ultrafiltration (UF) is a technology under development to selectively concentrate and recover valuable or regulated metal-ions from dilute process or waste waters. The polymers have a sufficiently large molecular size that they can be separated and concentrated using commercially available UF technology. The polymers can then be reused by changing the solution conditions to release the metal-ions, which are recovered in a concentrated form for recycle or disposal. Pilot-scale demonstrations have been completed for a variety of waste streams containing low concentrations of metal ions including electroplating wastes (zinc and nickel) andmore »« less

Removal of actinides from dilute waste waters using polymer filtration

Conference Smith, B F ; Robison, T W ; Gibson, R R

More stringent US Department of Energy discharge regulations for waste waters containing radionuclides (30 pCi/L total alpha) require the development of new processes to meet the new discharge limits for actinide metal ions, particularly americium and plutonium, while minimizing waste. We have been investigating a new technology, polymer filtration, that has the potential for effectively meeting these new limits. Traditional technology uses basic iron precipitation which produces large amounts of waste sludge. The new technology is based on using water-soluble chelating polymers with ultrafiltration for physical separation. The actinide metal ions are selectively bound to the polymer and can notmore »« less
Water-soluble chelating polymers for removal of actinides from wastewater

Conference Jarvinen, G D

Polymer filtration is a technology under development to selectively recover valuable or regulated metal ions from process or wastewaters. The technology uses water-soluble chelating polymers that are designed to selectively bind with metal ions in aqueous solutions. The polymers have a sufficiently large molecular weight that they can be separated and concentrated using available ultrafiltration (UF) technology. The UF range is generally considered to include molecular weights from about 3000 to several million daltons and particles sizes of about 2 to 1000 nm. Water and smaller unbound components of the solution pass freely through the UF membrane. The polymers canmore »« less

Removal of oxyanions from aqueous systems using polymer filtration (water-soluble metal-binding polymers with ultrafiltration)

Conference Rogers, Y C ; Santos, E C ; Robison, T W ; ...

The group V-A and VI-A elements exist in the environment as oxyanions. They enter the environment from both agricultural and industrial sources. The Kestersen reservoir hazardous to wildlife. Arsenic and antimony are used in pesticides and as hardners in alloys, bearings, and in storage batteries. All these metals are emitted during smelting operations. We have been able to remove As(V)/Se(V) from the 100 ppm level to very low levels using water-soluble metal-binding polymers with ultrafiltration. Arsenic contaminated drinking water from Europe was treated and the As level was successfully lowered to better than drinking water standards (<0.1 ppm). We willmore »« less
