B. Chemistry and Physical Properties:
Potassium monopersulfate compound is a free-flowing, white granular solid, soluble in water. It
is present as a component of a triple salt including potassium monopersulfate, potassium
sulfate and potassium bisulfate with the formula 2KHSO5·KHSO4·K2SO4. The oxidation
potential of this compound is derived from its peracid chemistry.
The compound provides powerful non-chlorine oxidation for a wide variety of industrial and
consumer uses. It’s applications may be found in oral hygiene formulations, pool and spa
shock and disinfections, paper recycling, printed circuit board etching, wool shrink proofing,
laundry bleaches, precious metal extraction process. The compound is an important auxiliary
agent in organic synthesis for oxidizing plenty of organics and functioning as the epoxy
oxidizer of the twin bonds of organic chemicals. It’s also a free radicle introductory agent in
many polymeric reactions. Potassium monopersulfate can be used to oxidize hydrogen sulfide
(H2S) and other reduced sulfur compounds, such as mercaptans, sulfides, disulfides, and
sulfites in waste water treatment. It’s also an oxygen releasing agent in aquiculture and low
temperature bleaching agent in detergent formulations.

D. Applications:
1、Denture Cleansers
Denture cleanser formulations containing at least 25% Potassium monopersulfate compound
provide excellent decolorization of food and other organic stains. Formulations usually include
sodium perborate monohydrate, sodium carbonate and/or bicarbonate, and may also include
citric acid, EDTA or DTPA chelants, flavor/fragrance, and food color. Cleansers are often
tabletted, but may be delivered in granulated form as sachets. The long shelf life of these
products requires moisture barrier packaging materials such as a metal or plastic tube or a
heat-sealed wrap of flexible reverse printed polyester laminated to foil which is extrusion
coated with a sealant layer of Surlyn ionomer resin.
2、Pool and Spa Shock
Potassium monopersulfate compound is used as an auxiliary oxidant (shocking agent) in
swimming pools and spas for the purpose of reducing the organic content of the water.
Treatment with Potassium monopersulfate compound on a regular weekly basis improves the
efficiency of
sanitizing chemicals such as chlorine or bromine by oxidizing and eliminating
contaminant waste, and restores sparkle and clarity to pool and spa water. Since Potassium
monopersulfate compound contains no chlorine, it will not combine with organic contaminants
to produce chloramines or generate irritating chloramine odors.
Potassium monopersulfate compound is gentle on pool surfaces. It dissolves quickly and
completely and will not bleach or fade vinyl liners or painted surfaces. The excellent solubility
of Potassium monopersulfate compound makes it easy to use -- simply broadcast it uniformly
over the pool water surface. Unlike chlorine-based shocking agents that superchlorinate the
pool, Potassium monopersulfate compound does not increase the chlorine level; therefore, the
pool need not be closed except for a short period to fully circulate the Potassium
monopersulfate compound.
3.Paper Recycling
Potassium monopersulfate compound is a convenient and effective processing aid for
repulping internal broke or a secondary fiber furnish. Paper products containing
polyimine/polyamide wet strength resins can be effectively repulped to make the same grade
paper. Potassium monopersulfate compound use has been demonstrated on a variety of
sanitary, food, packaging, and specialty papers containing wet strength resin and made from
different furnishes.
Unlike chlorine-based repulping agents, Potassium monopersulfate compound does not
produce absorbable organic halogens (AOX) or other chlorinated organics. It also does not
degrade the fiber or darken mechanical pulp. It is easier to handle and does not require any
additional
storage
or
delivery
equipment.
Under
optimum
conditions,
Potassium
monopersulfate compound reacts rapidly, thereby reducing the repulping time and increasing
the productivity of the pulper. It is effective under commonly found pulping conditions.
Potassium monopersulfate compound can also be used to repulp certain colored papers,
including decolorization of dyes. Dye destruction generally requires use of an additional
reactant which is added to the repulper separately.
Potassium monopersulfate compound can be delivered to the repulper either in specially
designed repulpable bags or by using an automated system fed from a bulk bag of Potassium
monopersulfate compound. Either method can provide accurate dosing to the repulper and
minimizes handling by operating personnel.
4.Printed Circuit Board Etching
Potassium monopersulfate compound is used as a microetchant for cleaning and preparing
copper printed wiring board surfaces. The superior etching performance of Potassium
monopersulfate compound is useful in plated-through-hole production in pattern and panel
plating, inner layer bonding, and prior to photoresist or solder mask application. This
microetchant is used in both dip and spray cleaning of inner layer copper surfaces, and results
in a sharply defined etch with greatly expanded surface area to assist in pre-lamination,
pre-oxide, and pre-plating operations. Etch rates from 0.25 - 2.5 µm/min (10 - 100 µin/min) can
be obtained by varying the Potassium monopersulfate compound concentration, acid
concentration, and temperature.
Potassium monopersulfate compound offers advantages over other mild etch solutions in etch
rate control, consistency of etch rate over a long period of time, and in waste treatment.
5. Wool Shrinkproofing
Potassium monopersulfate compound is used as an oxidizer for the treatment of wool to
prepare it for the application of shrinkproofing resins. In this application, Potassium
monopersulfate compound disrupts the surface of the wool and oxidizes cystine linkages in the
cuticle to give it anionic character which is ideal for attracting polyacrylic and polyamide resins,
with less damage to the wool than chlorine processing, and without the environmental damage
associated with chlorine use
6. Laundry Bleach
Potassium monopersulfate compound is an effective low-temperature non-chlorine laundry bleach
when formulated to provide at least 25 ppm of active oxygen in the wash water. Conventional
anhydrous alkalis and fillers can be used to attain a pH of 9 - 10, and to control dose. Potassium
monopersulfate compound can be used with colors; however, care must be taken to completely
dissolve Potassium monopersulfate compound before contact with damp fabrics to avoid dye
damage.
7.Environmental
(1)Oxidation of Reduced Sulfur
Potassium monopersulfate compound can be used to oxidize hydrogen sulfide (H 2S) in waste
streams. This provides a convenient method of de-odorizing a waste stream (or stack via
scrubbing) without the necessity of on-site manufacture or handling of hazardous chemicals
such as Caro's acid. Other reduced sulfur compounds, such as mercaptans, sulfides,
disulfides, and sulfites may also be oxidized. Analytical testing must be used to determine the
effect on the waste stream.
(2)Oxidation of Cyanide
Cyanide in waste streams from metal plating or mining operations can be oxidized rapidly
using Potassium monopersulfate compound. For dilute or small volume waste streams, an
Potassium monopersulfate compound -based waste treatment process can be convenient and
economical.
E.Handling and Storage
