Abstract: Proposed are a method of preparing a cesium adsorbent and a cesium adsorbent prepared thereby. The method includes (a) preparing a powder mixture of coal mine drainage sludge (CMDS) powder, sodium hydroxide (NaOH) powder, and sulfur (S) powder and (b) heat-treating the powder mixture to prepare a cesium adsorbent. The cesium adsorbent increases the active ion exchange of Na and Cs and the bonding of S—Cs when adsorbing cesium ions, resulting in an average of 5 times higher Cs removal efficiency and adsorption capacity under various conditions compared to CMDS since CMDS relies on cesium adsorption by simple physical and electrostatic attraction. Moreover, the cesium adsorbent is eco-friendly and has excellent economic efficiency by utilizing waste CMDS.

Abstract: Proposed is a method for estimating the mass of microplastics by using fluorescent staining. The method may include staining microplastic samples by using a Nile red solution, and capturing a fluorescent image of each of the stained microplastic samples after classifying the stained microplastic samples by mass. The method may also include analyzing the captured fluorescent image to quantify a fluorescence intensity thereof to build a database (DB) about a correlation between mass and fluorescence intensity of microplastics. The method may further include estimating a mass value of an unknown microplastic sample by comparing a fluorescence intensity of a fluorescent image of the unknown microplastic sample obtained by performing the staining and capturing of the unknown microplastic sample with data stored in the database.
