Sorption properties of fullerene-modified activated carbon with respect to metal ions

The prospects of modying of the activated carbon with microamounts of fullerenes, which can enhance its adsorption capacity with respect to metal cations by a factor of 2.5–5, are illustrated. The analysis of experimental data makes it possible to assume that silver ions are reduced on the carbon sorbent surface to metal silver, lead cations are sorbed due to the donor-acceptor interaction, and the copper ion sorption may lead to both the cation reduction to metal copper and the formation of complexes with different ligands preferentially with those containing an amino group.

Composite sorbents based on depleted fullerene soot

The production of fullerene soot with a fullerene content of no higher than 0.1 wt % by fullerene extraction with aqueous solutions of organic compounds has been investigated. It is possible and promising to prepare molded composite sorbents consisting of depleted fullerene soot and a binder namely, polyacryla-mide or a fluoropolymer.

New generation sorption systems

This article deals with sorption systems that are composite sorptive materials made in the form of block items consisting of elements for the supply and removal of energy of different forms. Examples of the use of thermal, electromagnetic, and light effects on sorptive materials of different nature for the control of the sorption process are considered. Definite constructional solutions in this scientific area are given.     

Technology of integrated usage of fullerene materials in sorbent production

Information about the main directions of the developing production technology of adsorbing materials, containing bound fullerenes, is given. The most promising is the usage of fullerene microquantities as a modifier of sorbing materials of diverse nature, which substantially increases their activity.     

Monitoring of Local Perturbations of the Multiplication Factor on Overloads in the Core of a Shut‐Down Reactor

A method of revealing the fact of existence (absence) of a local region in the reactor core with an anomalous value of the multiplication factor, detection of this region, and online monitoring of its movement throughout the volume of the core of a shutdown reactor during the entire period of overloading is proposed.
