It can be used in industrial processes as a sulfonating agent or as a source of sodium ions.\u003cbr\u003eIn photography, it can be used as a film developer, but it is rarely chosen. It tends to reduce the photosensitivity of the film and, if used incorrectly, quickly fades the image.\u003cbr\u003eIn biology, sodium hydrosulfite is used in biophysical experiments to lower the reduction potential of a solution.\u003cbr\u003eIn geology, it is used in chemical enhanced oil recovery to stabilize polyacrylamide polymers against degradation in the presence of iron.\u003cbr\u003eIt is also used in environmental applications to create a low Eh subsurface environment to reduce pollutants such as chromium.\u003cbr\u003eFurthermore, sodium hydrosulfite is used in soil chemistry experiments to determine the amount of iron not present in original silicate minerals.\u003cbr\u003eSodium hydrosulfite is used in chemical enhanced oil recovery to stabilize certain substances in the presence of iron.\u003c\/span\u003e\u003c\/p\u003e","brand":"特种化工电气解决方案服务商","offers":[{"title":"Default Title","offer_id":67603468025944,"sku":null,"price":0.0,"currency_code":"VND","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0604\/3051\/6312\/files\/tay-duong-cont-9886.jpg?v=1791001172","url":"https:\/\/duoduo1234.com\/en\/products\/sodium-hydrosunfite","provider":"特种化工电气解决方案服务商","version":"1.0","type":"link"}
