Abstract: PURPOSE: A method for reducing the toxicity of PCBs by reducing all chlorine atoms contained in PCBs (polychlorinated biphenyls) by using hydrogen, thereby converting the polychlorinated biphenyls into biphenyl. CONSTITUTION: The method comprises a step of mixing methanol solution saturated with sodium with a solution into which PCBs (polychlorinated biphenyls) is dissolved; a step of adding palladium-alumina catalyst to a mixed solution in which the PCBs solution is mixed with the methanol solution; and a step of applying ultrasonic waves to the mixed solution to which the palladium-alumina catalyst is added, wherein toxicity of chlorine molecules of PCBs is reduced by increasing activity of the palladium-alumina catalyst using ultrasonic waves, thereby stably conducting chemical reaction in which chlorine atoms of the PCBs are replaced with hydrogen of sodium formate.
