Abstract: Provided is an apparatus for collecting marine deposits. The apparatus includes: a piston corer for collecting a deep part of marine deposits; a corer for collecting a surface part of marine deposits; and a trigger body connecting the corer for collecting a surface part of marine deposits and the piston corer for collecting a deep part of marine deposits to each other while being maintained at a laterally set interval. The apparatus for collecting marine deposits can greatly save costs consumed to collect marine deposits and increase accuracy of collecting the marine deposits.

Abstract: Provided is a method of remediating cyanide-contaminated soil. The method is provided to remediate soil contaminated with cyanide and treat the cyanide, which includes collecting the soil contaminated with first cyanide in a solid state and second cyanide in a gaseous or dissolved state, dissociating cyanide by mixing the soil with an alkali washing solution, dissolving the first cyanide in a solid state in the washing solution, and transferring the second cyanide in a dissolved state dissociated from the soil to the washing solution, dissociating the soil from the washing solution, precipitating the first cyanide in a solid state by acidifying the washing solution containing the cyanide, and performing post-treatment on the first cyanide after the first cyanide precipitated in a solid state is dissociated from the washing solution.
