    Abstract: The formation of leachable mercury upon disposal or during TCLP testing of mercury vapor discharge lamps is substantially prevented by adding soluble copper salts which are capable of being reduced to elemental copper which deposits on aluminum and other metal surfaces thereby inhibiting formation of oxidized forms of mercury by chemical reaction or amalgamation.

    Abstract translation: 通过加入可沉淀在铝和其他金属表面上的能够还原成元素铜的可溶性铜盐,可以大大地防止在处理或在TCLP汞蒸气放电灯中处理或TCLP试验期间形成可浸出汞,从而通过以下方式抑制氧化形式的汞的形成: 化学反应或合并。
