International Classification:

B01J 4900

US Classification:

521 26, 521 28, 521 32, 525370

Abstract:

A method for regenerating strong-base anion exchange resins utilizing a sequential chemical displacement technique with new regenerant formulation. The new first regenerant solution is composed of a mixture of ferric chloride, a water-miscible organic solvent, hydrochloric acid, and water in which tetrachloroferrate anion is formed and used to displace the target anions on the resin. The second regenerant is composed of a dilute hydrochloric acid and is used to decompose tetrachloroferrate and elute ferric ions, thereby regenerating the resin. Alternative chemical displacement methods include: (1) displacement of target anions with fluoroborate followed by nitrate or salicylate and (2) displacement of target anions with salicylate followed by dilute hydrochloric acid. The methodology offers an improved regeneration efficiency, recovery, and waste minimization over the conventional displacement technique using sodium chloride (or a brine) or alkali metal hydroxide.

Abstract:

The invention relates to a class of phenoxy fluoro-alcohols, their preparation, and their use as phase modifiers and solvating agents in a solvent composition for the extraction of cesium from alkaline solutions. These phenoxy fluoro-alcohols comply with the formula: in which n=2 to 4; X represents a hydrogen or a fluorine atom, and R -R are hydrogen or alkyl substituents. These phenoxy fluoro-alcohol phase modifiers are a necessary component to a robust solvent composition and process useful for the removal of radioactive cesium from alkaline nuclear waste streams. The fluoro-alcohols can also be used in solvents designed to extract other cesium from acidic or neutral solutions.

Abstract:

Highly sensitive sensor platforms for the detection of specific reagents, such as chromate, gasoline and biological species, using microcantilevers and other microelectromechanical systems (MEMS) whose surfaces have been modified with photochemically attached organic monolayers, such as self-assembled monolayers (SAM), or gold-thiol surface linkage are taught. The microcantilever sensors use photochemical hydrosilylation to modify silicon surfaces and gold-thiol chemistry to modify metallic surfaces thereby enabling individual microcantilevers in multicantilever array chips to be modified separately. Terminal vinyl substituted hydrocarbons with a variety of molecular recognition sites can be attached to the surface of silicon via the photochemical hydrosilylation process. By focusing the activating UV light sequentially on selected silicon or silicon nitride hydrogen terminated surfaces and soaking or spotting selected metallic surfaces with organic thiols, sulfides, or disulfides, the microcantilevers are functionalized. The device and photochemical method are intended to be integrated into systems for detecting specific agents including chromate groundwater contamination, gasoline, and biological species.

Abstract:

Methods for the preparation of a stable, self-assembled monolayer on the silicon surface or metallic coating of a microcantilever are disclosed. The methods produce a microcantilever suitable as a chemical sensor. In a microcantilever produced using one version of the method, a metallic coating is disposed on a side of the microcantilever, a bridging atom is bonded to the metallic coating, a first spacer group is bonded to the bridging atom, a second spacer group is bonded to the bridging atom, and a chemical recognition agent is bonded to the first spacer group. In another version of the method, a silicon surface of a microcantilever is hydrogen terminated, and a calixarene chemical recognition agent is carbon linked to the silicon surface using photochemical hydrosilylation. Among other things, the calixarene may be bonded to a crown ether for ion detection or bonded to a area for the recognition of explosives by hydrogen bonding to nitro groups.
