Hydrogen peroxide surface-water samples

Figure 5. Hydrogen peroxide decay rate constants in surface-water samples from Sharpes Bay (in June and September), Jacks Lake, Ontario, Canada, from the East (Station 23), Central (Station 84), and West Basin (Station 357) of Lake Erie and the Chesapeake Bay, plotted as a function of bacteria...

Concentrations of hydrogen peroxide in atmospheric water samples such as rainwater are usually considerably higher than those determined in surface water samples. For example, Zika et al. (1982) found rainwater collected in southern Florida and the Bahamas to contain levels ranging from 1-7 x 10" M. Levels of up to 3 X 10 M were detected in southern California and Tokyo rainwater (Kok, 1980 Yoshizumi et al., 1984), although the usual hourly mean concentration was about an... 

Properties (pure anhydrous) density of solid, 1.71 g/cc, density of liquid 1.450 g/cc at 20C, viscosity, liquid 1.245 cP, surface tension 80.4 dynes/cm at 20C, fp -0.41C, bp 150.2C. Soluble in water and alcohol. (Solutions) pure hydrogen peroxide solutions, completely free from contamination, are highly stable a low percentage of an inhibitor such as acetanilide or sodium stannate, is usually added to counteract the catalytic effect of traces of impurities such as iron, copper, and other heavy metals. A relatively stable sample of hydrogen peroxide typically, decomposes at the rate of approximately 0.5% per year at room temperature.
