Abstract: A preparation method for a nanopore starch-based adsorbent. The method mainly comprises: constructing a large number of lamellar crystals on surfaces of starch granules, and inducing the formation of a nano-scale pore channel structure by means of the lamellar crystals. A large number of control tests have proved that the flaky crystals have direct influence on the formation of the nano-scale pore channel structure. The construction of a pore channel structure in a starch matrix material greatly increases the specific surface area, and improves the adsorption properties. In addition, the method is beneficial to the introduction of functional particles (magnetic particles), and avoids the problem of pore channel blockage due to first forming pores and then introducing functional particles.

Abstract: In a method for enriching and separating an anaerobic fiber-degrading bacterium on the basis of cellulosic magnetic nanoparticles, the cellulosic magnetic nanoparticles are prepared by coating cellulose on the surface of a magnetic nanomaterial. Bacteria attach to the cellulosic magnetic nanoparticles. Anaerobic fiber-degrading bacteria degrade the cellulose and then detach from the cellulosic magnetic nanoparticles, and the anaerobic fiber-degrading bacteria are obtained by means of separation using a magnet. The magnetic nano-separation technology can be used as a new technology to efficiently separate anaerobic fiber-degrading bacteria.

Abstract: Disclosed is a method for preparing a strontium-82/rubidium-82 generator. The method includes: filling a column volume with a sorbent made of hydrated tin (IV) oxide; passing through the column an initial solution with strontium-82 radionuclide, which also contains ions of stable isotopes of calcium and strontium; and washing out rubidium-82 with a saline solution of 0.9% sodium chloride. In order to achieve a breakthrough of strontium-82 or strontium-85 below permissible levels, 0.01 and 0.1 kBq per 1 MBq 82Rb, respectively, when passing not less than 17 liters of saline solution through columns with a volume of not less than 1.6 cm3 and a dry sorbent weight of not less than 3.8 g, a specific activity of strontium-82 in the initial solution is not less than 90 GBq (2400 mCi) per mg of stable strontium cations for a generator with an activity of 3700 MBq (100 mCi).

Some embodiments provide biogenic activated carbon that is responsive to a magnetic field. A continuous process for producing biogenic activated carbon comprises countercurrently contacting, by mechanical means, a feedstock with a vapor stream comprising an activation agent including water and/or carbon dioxide; removing vapor from the reaction zone; recycling at least some of the separated vapor stream, or a thermally treated form thereof, to an inlet of the reaction zone(s) and/or to the feedstock; and recovering solids from the reaction zone(s) as biogenic activated carbon.
