Introduction In a previous paper  referred to as paper #1, it was demonstrated that the Lorenz-Mie (L-M) cross section for light scattering from monodisperse microspheres suspended in water gave a good description of absorbance measurements with a commercial spectrometer with an integrating sphere (IS) detector for wavelengths greater than 300 nm.
On the other hand, the highest absorbance sensitivity for substances like creatinine, uric acid and phosphate was obtained in the wavelength range of 220-270 nm .
We set out to determine if the absorbance (log transmittance) as measured by an integrating sphere spectrophotometer of coatings with absorbing, reflecting, or scattering pigments was linearly proportional to the layer thickness.
If we plot absorbance or transmittance against frequency or wave number, the result is an infrared spectrum.
Contents were then centrifuged at 2000 g for 5 min and the absorbance of the supernatant was taken at 760 nm.
In the absence of cupric ion, the wavelength of maximum absorbance by Zincon is 490 nanometers (nm).
