The preparation method comprises the following steps: mixing a carbon black slag powder, porous aluminum oxide and a polar solution, calcining same, then mixing the magnetic powder with a cross-linking agent, then injecting same into a forming mold for treatment and formation, then stripping same, and activating same, so as to obtain the magnetic aluminum-based adsorbent. The magnetic aluminum-based adsorbent prepared by the preparation method has a relatively high adsorption property and can adsorb low-concentration metal ions in wastewater generated by wet recovery of waste batteries well.

Polypropylene (PP) and polyethylene (PE) blends derived from plastic waste streams and a method to prepare reusable oil sorbents. A method includes separating plastics of group-A from group-B using a float-sink technique, where group-A comprises various PP and PE materials, and group-B comprises polystyrene, polyethylene terephthalate, and polyvinyl chloride; dissolving the group-A plastics in a solvent; adding a cavity forming agent to the solution; applying the solution onto a solid substrate through spin-coating followed by controlled heating; and extracting the cavity forming agent, obtaining a thin film sorbent with swellable cavities for oil sorption. The film contains 400-800 swellable 3D cavities/cm.sup.2, each cavity capable of swelling 20-30 times the thickness of the film when contacted with oil. The method improves compatibility of PP-PE blends without using compatibilizers, resulting in high oil uptake capacity due to swellable cavities, and reusability of sorbent with an oil recovery of more than 98%.

Provided are an adsorbent for trapping a radioactive iodine gas generated in a process of oxidizing a nuclear fuel at a high temperature after use and a method of preparing the same, and more particularly, a radioactive iodine gas adsorbent which is formed of bismuth as a main component, thereby exhibiting an excellent radioactive iodine gas trapping capability and an excellent thermal stability after trapping, and a method of preparing the same.

An adsorbent for trapping a radioactive iodine gas prepared by a method of preparing an adsorbent for trapping a radioactive iodine gas according to the present disclosure may effectively trap a radioactive iodine off-gas generated in a nuclear fuel pre-treated oxidizing process after use.

Particularly, the adsorbent may trap iodine in a larger amount, which is twice or more, than a silver-containing zeolite widely used to trap a radioactive iodine gas, and the trapped iodine forms a stable compound, which is more advantageous for long-term storage.

In addition, since an iodine gas is trapped using inexpensive bismuth, instead of expensive silver, in consideration of trapping a large amount of a radioactive iodine gas, the adsorbent has very excellent economic feasibility.
