摘要
Solid waste material which contains arsenic and/or mercury impurities is encapsulated in a cured polysulfide polymer so as to alleviate leaching of arsenic and/or mercury into aqueous liquids. Preferably, the solid waste material is first extracted with an alcohol such as ethanol or, alternatively, treated with an oxidizing agent such as aqueous hydrogen peroxide and then substantially dried before the encapsulation with the polymer is carried out.
