As the main component of radioactive wastewater, the cesium ion has seriously endangered the environment and human health. Prussian blue nanoparticles (PB NPs) are used as adsorbents for the purification of cesium-containing wastewater because of their ability to selectively adsorb cesium ions. In this work, novel magnetic Prussian …

The cesium removal system is a key part of the Site's Direct Feed Low Activity Waste (DFLAW) program, an assembly of several highly interdependent projects and infrastructure that will operate together to vitrify and safely dispose of millions of gallons of low-activity tank waste once operational. "This is an exciting new era in our ...

This review systematically summarized and analyzed the recent advances in the crown ethers and calixarenes derivatives for cesium separation, especially focusing on the adsorbents based on extractants for cesium removal from aqueous solution, such as the grafting coordinating groups (e.g. crown ether and calixarenes) and coordinating …

In this work, the cesium (Cs) removal from contaminated water was assessed using Mangrove charcoal modified adsorbent to understand the usability of the adsorbent. The Mangrove charcoal was oxidized by nitrification process for introducing the carboxyl (-COOH), carbonyl (C O) and hydroxyl (-OH) groups for sensitivity to Cs ion.

Magnetic biochar functionalized with Prussian blue (MBC-PB) was synthesized as an effective and economical adsorbent for removing cesium from aqueous solutions. Its physicochemical properties were characterized and cesium adsorption experiments were conducted. The cesium adsorption reaction was mainly physisorption …

The evolution of cesium removal technology. In 2008, Peterson and other researchers at PNNL successfully demonstrated in a pilot project that they could remove cesium using a system set next to a nuclear waste tank. Plugging a removal system directly into a single tank was shown to be a cost-effective approach.

Cesium removal technology had to be accelerated and deployed quickly in response to the accident. "Within days after the event, I headed to DC to do a review of what technology should be used ...
