A number of other inorganic oxidizing agents has also been reported for sulfide oxidation which include [Ru(bpy)2(0)PR3][C104],419 Zn(Bi03)2/ AcOH420 and potassium monopersulfate on wet alumina.421... 

II state, [PFe=0], is the only product detected spectroscopically. The kinetics of equations (50 56), including the formation of the Compound I precursor, have been studied in detail by several groups. The Compound I state is readily reached by reaction of an iron(ni) porphyrin with iodosylbenzene, potassium monopersulfate, or an amine N-oxide, and these reagents are frequently used for generation of the hydroxylation catalysts of the Compound I level that are discussed in Section 9. 

The composition of the oxidizing agent Oxone is 2 KHS05 KHS04 K2S04. The active component potassium monopersulfate (KHSO5, potassium peroxomonosulfate) is a salt from Caro s acid H2SO5.

A second area of MnP model chemistry has dealt with Mn11 oxidation by Fe-porphyrin systems. An early example suggested that Mn11 in the presence of excess pyrophosphate could be catalytically oxidized to Mn1" by an Fe-porphyrin system. In these experiments, sulfo-nated porphyrins were utilized, and the co-oxidant was potassium monopersulfate. Co-substrates, such as veratryl alcohol, were reported to enhance the rate of Mn11 oxidation (468).

Stability of oxidizers is also a concern. Halogenated products generate chlorine and bromine. Both are irritating, poisonous gases. Other materials decompose with the production of less objectionable elements or compounds. For example, the relatively stable potassium monopersulfate (Oxone), emits oxygen when it decomposes but at elevated temperatures, may also generate sulfuric acid, sulfur dioxide, or sulfur trioxide [6.3.2.3]. Small amounts of moisture (and, depending on the product, many other chemicals) reduce the stability of all oxidizers. 

Handling, Storage, and Precautions the Oxone triple salt 2KHS05-KHS04-K2S04 is a relatively stable, water-soluble form of potassium monopersulfate that is convenient to handle and store. Oxone has a low order of toxicity, but is irritating to the eyes, skin, nose, and throat. It should be used with adequate ventilation and exposure to its dust should be minimized. Traces of heavy metal salts catalyze the decomposition of Oxone. For additional handling instructions, see the Du Pont data sheet. 

Potassium monopersulfate (in fact a triple salt 2KHSO5.KHSO4.K2SO4, Curox ) was a gift of Interox. Mn-TMPyP was synthesized as previously described. Alkaline phosphatase (EC 3.1.3.1, from Escherichia coli, type in) was from BRL. T4 polynucleotide kinase (EC 2.7.1.78), terminal deoxynucleotidyl transferase (EC 2.7.7.31), [y- P]ATP and [a- P]ddATP were from Boehringer. Maxam-Gilbert kit was from NEN (Dupont). Other chemicals were from Sigma or Aldrich.

The peroxide of sulfuric acid, monoperoxysulfuric acid, is difficult to handle, but its triple salt potassium monopersulfate (KMPS = 2KHS05 KHS04 K2S04) is storage-stable. Its fast dissolution rate in cold water supports its powerful oxidizing and disinfection properties. Intrinsic acidic properties, however, make KMPS (pH = 2.3) less suitable for use in alkaline formulations. 

The reaction of potassium monopersulfate with certain ketones at a weakly alkaline pH results in the formation of dioxiranes [55]. By modeling the ketone, bleaching optima in a neutral or alkaline medium can be tailored to match the desired application pH. Best results are achieved with solid cyclohexanone derivatives [56], sugar-based ketones (SK) [57] (bleaching optimum at pH 10), or with substituted aminoacetones such as DMAA (bleaching optimum at pH 8-9).
