UN PROCEDIMIENTO PARA LA ELIMINACION DE TIOSULFATOS DE UNA SOLUCION ACUOSA ALCALINA DE LOS MISMOS |
摘要 |
<p>Aqueous alkaline sulfidic waste effluents are often subjected to air oxidation processes that for economic sizing oxidize the sulfides only to thiosulfates. Thiosulfates are still immediate oxygen demanders and thus their concentration in the effluent must normally be reduced to below a threshold level before the effluent can be discharged. The effectiveness of hydrogen peroxide for this purpose can be significantly improved both as to rate of reaction and extent of removal by employing a copper catalyst in solution.</p> |
