Ozone absorption coefficients
WebThe average amount of ozone loss in the stratosphere is estimated to be 5 percent per decade (an average depletion rate of 0.51 percent per year). The worldwide loss of ozone has become a major environmental concern, since it results in less protection to life on the earth’s surface from the harmful ultraviolet solar radiation. WebJun 1, 2016 · In the determinations of ozone concentration in aqueous solutions by direct spectrophotometry, we recommend the value of the molar absorption coefficient ε (О 3) 260 = 3000 M –1 cm –1.
