persulfate การใช้

• Oxidation with ammonium persulfate and dilute caustic soda gives bismuth tetroxide.
• Chemicals housed in the facility included ammonium persulfate and sodium chlorite.
• The persulfate and iron react underground to produce the sulfate radicals.
• Alternatively the compound can be synthesized from salicylic acid via Elbs persulfate oxidation.
• :persulfate is a possibility SO 5 2 ".
• Persulfate is a newer oxidant used in ISCO technology.
• Typical equations showing persulfate generation of hydroxyl radicals follows.
• Additionally, current persulfate activation methods often stall resulting in sub-optimal results.
• The most common oxidant is ammonium persulfate.
• Potassium persulfate is less soluble ( cfr.
• It has been noted that persulfate salts are a major cause of asthmatic effects in women.
• It is suggested that the phenol in many cases is a catalyst converting the persulfate into a sulfate.
• Additionally, each mole of persulfate creates one mole of oxidizer ( sulfate radical or hydroxyl radical ).
• These radicals have low atomic weights while the persulfate molecule has a high atomic weight ( 238 ).
• "' Potassium persulfate "'is the inorganic compound with the formula S 2 O 8.
• The reaction is disadvantaged by low chemical yields with recovery of starting material and complete consumption of the persulfate.
• Stephenson et al . reported using aniline derivatives with sodium nitrite in 96 % sulfuric acid and ammonium persulfate.
• New research has shown that Zero Valent Iron ( ZVI ) can also be used with persulfate with success.
• The persulfate and the iron are not mixed beforehand, but are injected into the area of contamination together.
• Other inorganic radicals that show this type of reactivity are sulfate radical ions ( from ammonium persulfate ) and hydroxyl radicals.
