- Model SR - ISCO Reagent (Cylinder)


RemOx SR ISCO reagent (sustained release) was developed to meet a need for more passive treatment. RemOx SR is a solid paraffin wax matrix with ~80% potassium permanganate. It can be manufactured as a cylinder, chipped for barrier applications, or further processed for hydrofracturing into low permeability media.

RemOx SR ISCO reagent has been specifically manufactured for environmental applications such as remediation of soils and associated groundwater. This product can be used to degrade a variety of contaminants including chlorinated solvents, polyaromatic hydrocarbons, phenolics, organo-pesticides, and substituted aromatics.

RemOx SR is manufactured with RemOx® S ISCO reagent. RemOx S meets Carus specifications and a certificate of analysis is available upon request for the RemOx S product used to manufacture RemOx SR.

RemOx SR was developed to provide a sustained release of potassium permanganate for soil and groundwater treatment of: chlorinated ethenes, phenolic compounds, polyaromatic hydrocarbons, RDX, HMX, and various pesticides. RemOx SR can be emplaced in the subsurface using direct push technology or suspended into existing wells. It is recommended prior to installing RemOx SR cylinders a dispersant is added such as sodium hexametaphosphate (SHMP). This keeps MnO2 solids suspended in groundwater, preventing their deposition and their potential impact on oxidant release and distribution. This technology can be used for source treatment as well as barrier applications.

Postal regulations:

Information applicable to packaging of oxidizers for shipment by the U.S. Postal Service to domestic and foreign destinations is readily available from the local postmaster. United Parcel Service accepts 25 lbs as largest unit quantity properly packaged; (consult United Parcel Service). Regulations concerning shipping and packing should be consulted regularly due to frequent changes.

RemOx® SR ISCO reagent is compatible with many metals and synthetic materials. Natural rubbers and fibers are often incompatible. Solution pH and temperature are also important factors. The material must be compatible with either the acid or alkali also being used.

In neutral and alkaline solutions, RemOx SR is not corrosive to iron, mild steel, or stainless steel; however, chloride corrosion of metals may be accelerated when an oxidant such as permanganate is present in solution. Plastics such as polypropylene, polyvinyl chloride Type I (PVC I), epoxy resins, fiberglass reinforced plastic (FRP), Penton, Lucite, Viton A, and Hypalon are suitable. Teflon FEP and TFE, and Tefzel ETFE are best. Refer to Material Compatibility Chart.

Aluminum, zinc, copper, lead, and alloys containing these metals may be (slightly) affected by RemOx SR solutions. Actual studies should be made under the conditions in which permanganate will be used.

Protect containers against physical damage. Eye protection should also be worn when handling RemOx SR as a solid or in solution. Avoid breathing vapors or mists of the wax. Exposure or inhalation may cause irritation.

RemOx SR is stable and will keep indefinitely if stored in a cool, dry area in closed containers. Concrete floors are preferred to wooden decks. To clean up spills and leaks, follow the steps recommended in the SDS or eSDS. Be sure to use goggles, rubber gloves, and respirator when cleaning up a spill or leak.

Avoid contact with acids, peroxides, and all combustible organic or readily oxidizable materials including inorganic oxidizable materials and metal powders. With hydrochloric acid, chlorine gas is liberated. Avoid heating wax to 200° C (392° F) in the presence of potassium permanganate. RemOx SR is not combustible, but it will support combustion. It may decompose if exposed to intense heat. Fires may be controlled and extinguished by using large quantities of water. Refer to the SDS or eSDS for more information.
