Abstract;This paper explains the following items on the titled research: 1) Objectives; utilization of molten slug (I) in environmental conservation, 2) approach; Capture effect of lead ion in polluted water by crushed and crystallized I was studied in a lead solution (lead acetate, lead nitrate and lead chloride), 3) results; I captured lead in about 10 mg/g, and is thus sufficiently useful. Precipitation by hydroxide salt formation dominated absorption. XRD and IR analysis identified the salt to be hydroxyl lead carbonate. Leachate of I, which contains calcium, provided similar reaction products, including laurionite. An aqueous solution of calcium hydroxide also provided similar reaction products and 4) conclusion; Calcium oxide contained in I showed main role in lead capturing and removal.
