Abstract

A method and a system for recycling a metal from a lithium secondary battery are provided. In the method for recycling a metal from a lithium secondary battery, a cathode active material mixture containing lithium is prepared. A lithium precursor is produced by reducing the cathode active material mixture. A lithium precursor aqueous solution is formed by dissolving the lithium precursor in water. The lithium precursor aqueous solution is passed through an aluminum adsorption resin column to adsorb aluminum to the aluminum adsorption resin column. A first treatment liquid including distilled water is injected into the aluminum adsorption resin column at a flow rate of 100 L/hr to 1,200 L/hr to obtain a regenerated aluminum adsorption resin column from which aluminum is desorbed.

Abstract

Proposed is a method of analyzing microplastic particles in a water system. The method includes providing raw water containing microplastic particles, freezing and thawing the raw water at least once to generate microplastic aggregates in the raw water, recovering the microplastic aggregates, and analyzing the recovered microplastic aggregates. According to the method, the microplastic particles are precipitated in the water system without the use of an additional coagulant, whereby the effect of coagulants on the subsequently recovered microplastic aggregates may be ruled out. In addition, the process configuration is simple because the aggregates can be separated from the supernatant without using any additional treatment process.

Abstract

A method for recovering active metals of a lithium secondary battery may supply a cathode active material mixture to a fluidized bed reactor including a reactor body. A reaction gas may be introduced from a lower portion of the fluidized bed reactor to form a fluidized bed including a preliminary precursor mixture within the reactor body. The fluidized bed portion that has entered the upper portion of the fluidized bed reactor may be cooled to descend it into the reactor body, and then a lithium precursor may be recovered from the preliminary precursor mixture. Accordingly, a terminal velocity of the preliminary precursor is reduced, such that even if the particle size of the preliminary precursor is fine, loss due to scattering may be prevented.

Abstract

Provided is a carbon dioxide absorbent including an ionic liquid including an imidazole-based anion and an aliphatic alcohol, and since an alcohol solvent included in the carbon dioxide absorbent according to one embodiment has low toxicity and a very high boiling point, the carbon dioxide absorbent has no problem of release into the atmosphere and consequent environmental pollution, and is chemically stable to significantly lower the possibility of release of decomposition products into the atmosphere. In addition, the carbon dioxide absorbent is also effective, since it may absorb carbon dioxide with a higher equivalent than an absorbent input equivalent, and has low regeneration energy so that carbon dioxide is easily desorbed.
