4.4 Chemical properties
Sodium permanganate is a very strong oxidising agent.
It is soluble in water and dissolves in various organic solvents (methanol, ethanol).
The reaction with organics can be violent and is not recommended.
It decomposes at a high temperature and also in the presence of concentrated acids, hydrogen peroxide
and organic compounds in general.
It hydrolyses very slowly in contact with air, reducing to manganese dioxide (MnO ), a solid, brown to
black colour product.

5 Purity criteria
5.1 General
This document specifies the minimum purity requirements for sodium permanganate used for the
treatment of water intended for human consumption. Limits are given for impurities commonly present
in the product. Depending on the raw material and the manufacturing process other impurities may be
present and, if so, the user and when necessary relevant authorities shall be notified.
Users of this product should check the national regulations to clarify whether it is of appropriate purity
for treatment of water intended for human consumption, taking into account raw water quality,
required dosage, contents of other impurities and additives used in the product not stated in this
product standard.
Limits have been given for impurities and chemical parameters where these are likely to be present in
significant quantities from the current production process and raw materials. If the production process
or raw materials leads to significant quantities of impurities, by-products or additives being present,
the user shall be notified.
5.2 Composition of commercial product
The sodium permanganate is usually available in a concentrated solution with a concentration within
the range of mass fraction of 20 % to 40 %.
The concentration of sodium permanganate solution shall be equal to or greater than the manufacturer
specified value.
5.3 Impurities and main by-products
The content of manganese dioxide (insoluble matter) shall be no more than a mass fraction of 0,055 %.
NOTE The product can contain fluoride or hexafluorosilicate. At typical levels of dosing, the added fluoride
would be less than 40 µg/l.
5.4 Chemical parameters
The content of chemical parameters shall conform to the requirements specified in Table 2.
Table 2 — Chemical parameters
