    • PURPOSE: A method of removing contaminant is provided to use magnetic-cored Dendrimer with various functional groups, absorb and remove effectively not only a heavy metal but also hydrophilic or hydrophobic contaminants, and is used as a chelating agent for obtaining hydrophilic or hydrophobic absorbents, heavy metals and precious metals, and is applied for wastewater treatment plant, soil contaminant processing facilities, nuclear waste processing facilities, facilities for water waste from waste disposal sites and mines. CONSTITUTION: Magnetic-cored Dendrimer comprises any repetitive molecular structure in(1)-(4) structural formulas. In(1)-(4) structural formulas, MNP is a magnetic nano particle and an anion nano particle. A method of manufacturing magnetic-cored Dendrimer with a repetitive molecular structure of structural formulas(1) follows chemical equation 1. A method of manufacturing magnetic-cored Dendrimer with the repetitive molecular structure of structural formula(2) follows chemical equation 2. A method of manufacturing magnetic-cored Dendrimer with the repetitive molecular structure of structural formulas(3),(4) follows chemical equation 3, 4 respectively. A method of removing contaminants to use magnetic-cored Dendrimer comprises the following steps: a step to absorb contaminants by using magnetic-coed Dendrimer, a step to remove magnetic-cored Dendrimer with contaminants by using a magnet. A contaminant is cadmium. Cadmium is in solution more than pH 4. Magnetic-cored Dendrimer with contaminants is treated less than pH 4, to remove the contaminants from magnetic-cored Dendrimer, and is also re-used for removing contaminants.
