Recovery of the Effective Components in the Waste Liquor of Chemically Modified MnO₂ Production

The effective components in the waste liquor of chemically modified MnO₂ are analyzed by means of complex titration method. The recovery methods for the effective components and their economic benefits are also discussed in the paper. The results show that it not only can reduce the production cost, but also is of great advantage to environmental protection to chemically modified MnO₂ production.
