With sodium hyposulphite standard solution used in titration and starch developing agent as indicator,iron content can be determined.
以硫代硫酸钠标准溶液漓定,以淀粉显色为指示剂,可测定铁含量。
After comparison,sodium hyposulfite is the preferred absorbent,which the resultant has no influence on the environment with sodium hyposulfite over absorbed dose.
比较,硫代硫酸钠吸收量大,物对环境没有影响,为首选吸收剂。
Using sodium hydrosulphide or sodium thiosulfate as materials,the production cost of TGA is low.While,a high content of TGA can be obtained with thiourea as reactant.
本文对巯基乙酸的合工艺进行了比较研究,认为硫氢化钠法和硫代硫酸钠法本低,适宜于选矿用巯基乙酸的,而硫脲法可得到较高浓度的巯基乙酸。
