Chromium is very important metal used in various industrial processes such as textile industries, nuclear power plant, pulp production, electroplating, paint and pigment manufacture. These activities produce significant quantities of wastes containing heavy metals generating water and soil pollution. In trace amounts, chromium serves as an essential element for fat and glucose metabolism as well as the stabilizer of proteins and nucleic acids [Chwastowski J, Kołoczek H, 2013]. However, at higher concentrations it is extremely toxic and mutagenic especially in its oxidized form Cr(VI). Experiments for continous removal of 10 mM Cr(VI) and 10 mM Cr(III) from aqueous solutions using Canadian Peat and Coconut fiber as a sorbents were conducted. The reduction process of Cr(VI) was carried out with the use of L-band (1,2 GHz) electron paramagnetic resonance spectrometer.
