应用
Sodium metabisulfite is used as an active ingredient in campden tablets, as a cleaning agent for potable water reverse osmosis membranes, as a preservative and an antioxidant in food. It also acts as a corrosion inhibitor in oil and gas industry, as a bleaching agent in the production of coconut cream, as the source of sulfur dioxide and in the destruction of cyanide in commercial gold cyanidation processes. It is utilized in the precipitation of gold from auric acid as well as in the waste water treatment to remove hexavaent chromium as trivalent chromium by precipitation after reduction. Further, it is used in photography. In addition, it plays as an oxygen scavenger to eliminate the dissolved oxygen in wastewater and in pipes.

产品说明

一般描述

焦亚硫酸钠(MBS，二亚硫酸钠)是二硫(焦亚硫酸盐)酸的钠盐。也常作为防腐剂添加到各种食品和葡萄酒中。

应用

偏亚硫酸钠可通过自由基聚合引发聚丁二烯交联。在各种研究中，可用于预防 6-羟基多巴胺 (6-OHDA) 和 6-OHDA HBr 储备液制备过程中的氧化(作为抗氧化剂)。
