Optical Properties of Iron Pillared Clays as Catalysts for Heterogeneous Photo-Fenton Process

Optical properties of iron pillared clays (Fe-PILCs) were determined by using spectrophotometer measurements coupled with the solution of the radiative transfer equation (RTE). The specific absorption and scattering coefficients, as well as the phase function for scattering, were obtained as a funct...
