A method of Extraction and Recovery of mercury from gas containing gaseous Elemental Mercury.

摘要

A method of extraction of mercury from gases containing gaseous elementary mercury comprising treating said gases in a closed circuit with an aqueous solution containing 0.1-300 mmol/l mecury(II)-ions and at least double that content of ions with the ability to form soluble complexes with mercury(II)-ions whereafter mercury absorbed in solution is recovered and the solution recirculated.
