Process for the removal of heavy metals from aqueous liquids |
| abstract |
The invention relates to a process for the removal of heavy metal ions, particularly chromium, lead and/or zinc ions, from aqueous liquids by precipitation wherein the aqueous liquid containing the heavy metal ions and an aqueous liquid containing a base which precipitates the heavy metal ions in the form of their hydroxide or basic salt are added simultaneously to an amount of water at a pH between 5 and 10 and a temperature between 60 and 100°C and the pH and the temperature are maintained in the specified ranges during the precipitation. |
