Poster summary

The study focuses on the adsorption of 2 model pollutants (methyl green organic dye and copper (2+) ions as part of copper sulfate) on samples of materials (rice husk, wheat bran, peat and coal), carbonized in a fluidized-bed catalyst reactor at high temperatures (465,550,600 oC). Using spectrophotometry, the pollutant concentration before and after the adsorption process were analyzed in order to calculate the adsorption capacities of the materials. This way thermodynamic and kinetic experiments were performed, as a result of which a representative adsorption and kinetic models were chosen. Several parameters were also calculated, such as activation energy of the process and the equilibrium constant. The general adsorption capacity experiment was also conducted in order to determine the most and least effective sorbents among the studied samples.
