Abstract
In order to work out the technology of the higher grade manganese chloride tetrahydrate from waste Zinc-Manganese batteries,manganese content in it must be detemeined accurately.A method is used to deter mine manganese content by titration of NaNO_3-Na_3AsO_3 solution and with AgNO_3 as catalyst.Meamwhile,the solution of the sample,smoking and oxidation degree are tested.The results shown this method is convenient and rapid and exact.Recoveries of the manganese are in the range of 98.6%~101.9%.
