Abstract
The accumulation of arsenic in solid, liquid and gaseous waste of metallurgical production is an acute problem. Deposition of arsenic by sodium hydrosulfide is an effective and fast method of arsenic removal from solutions. The paper proposes a reactor design procedure for extraction of As (III) using the sulfide technology from washing solutions for wet gas scrubbing in sulfuric acid production. The paper takes into consideration the optimum parameters for removal of arsenic from solutions: the specific consumption of sulfide sulfur per1 kgof arsenic, the concentration of As (III) ions in the solution, the rate of sodium hydrosulfide feeding into the solution, and the hydrodynamic regime of the reactor. The obtained results are useful for design of experimental-industrial reactors used in dearsenication of solutions.
