METHOD OF REDUCING THE ODOUR OF SULPHUR-BOUND PRODUCTS

摘要

Method of reducing the odour of sulphur-bound products, in particular modified sulphur or sulphur concrete, comprising contacting the sulphur-bound products with a bleaching agent, like e.g. sodium hydrochloride or hydrogen peroxide. The resulting sulphur-bound products emit reduced levels of sulphur-containing gases such as H2S and SO2 and have a reduced odour.
