Persulfate - Model SR -ISCO Reagent

Persulfate SR is manufactured with sodium persulfate. Sodium persulfate meets specifications for assay.

Assay >98.2% as Na2S2O8
Formula Na2S2O8 in paraffin wax
Formula Weight Na2S2O8: 238.1 g/mol
Wax: not determined
Form Extruded solid of granular crystalline inside wax
Congealing point of wax is 54-57° C/ 129-134° F
Paraffin wax will start to melt at 55° C/ 132° F

Sodium persulfate crystals or granules are white encapsulted in a clear wax. Standard size is 2.5 in (6.4 cm) diameter by 18 in (45.7 cm) long with 70-75% by weight Na2S2O8.

Persulfate SR was developed to provide a sustained release of sodium persulfate for soil and groundwater treatment. Persulfate SR can be emplaced in the subsurface using direct push technology or suspended into existing wells. This technology can be used for source treatment as well as barrier applications.

2.5 in (6.4 cm) by 18 in (45.7 cm) cylinder - Qty 6/box Corrugated box that is 12.5 in (31.75 cm) by 10.625 in (26.987 cm) by 22 in (55.88 cm) with foam insert. Weight of box is 3.303 lbs (1.498 kg). Weight per cylinder is 6.348 lbs (2.879 kg) or 38.088 lbs (17.276 kg) per box. Total weight of box and cylinders is 41.391 lbs (18.774 kg). (Domestic and international)

Specialty packaging above was designed to insure delivery of cylinders without breakage.

Persulfate SR ISCO reagent is compatible with materials including butyl rubber, EPDM, fiber reinforced plastic, glass, neoprene, plexiglass, polyethylene, PVC, stainless steel, Teflon®, viton. Incompatible materials include aluminum, carbon steel, galvanized pipe, monel, nitrile rubber, brass, copper, iron, and nickel. Refer to Material Compatibility Chart.

Actual studies should be made under the condition in which Persulfate SR will be used.

Protect containers against physical damage. Eye protections should also be worn when handling Persulfate SR. Avoid breathing vapors or mists of the wax. Exposure or inhalation may cause irritation.

Store in a cool, clean, cry place away from point of sources of heat. 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, hallides, combustible materials, most metals and heavy metals, oxidizable materials, other oxidizers, reducing agents, cleaners, and organic or carbon containing compounds. Fires may be controlled and extinguished by using large quantities of water. Refer to the SDS or eSDS for more information.

Persulfate SR is stable under normal conditions. Do no expose to sparks, heat, open flames, or hot surfaces. It is important that smoking is not allowed in proximity to Persulfate SR. Do not cut with any cutting tools which could produce friction (i.e. hand saws, circular saws, reciporcal saws, etc.) as it may cause ignition of the material.
