This paper studies nitrogen oxide reduction by means of ammonia in a flow reactor with a fixed bed of the Polish carbon sorbent AKP-5. The kinetic curves (t), showing the dependence of the degree of reduction of nitrogen oxide on time have been determined for four inlet NO concentrations. On the basis of the degree of NO reduction determined for the steady state conditions, a simplified model of the kinetic equation has been developed and verified. The results obtained are very important for environmental protection.

Activated carbon is an effective sorbent for removing organic and inorganic contaminants from aqueous solutions. In conducted experiments, granulated activated carbon (GAC) was used to examine the adsorption processes of heavy metals (Cd, Cu, Ni, Pb and Zn). Studies (performed in batch system) were carried out as a function of time, heavy metals concentration and pH values. The obtained results show that GAC effectively removes mentioned metals. Numerous kinetic models were used to investigate the mechanism of adsorption processes. Using the Langmuir isotherm, the maximum adsorption capacities were calculated to be 3.010, 3.662, 4.430, 3.800 and 4.169 mg·g–1 for Cd, Cu, Ni, Pb and Zn, respectively, in neutral conditions and 2.684, 2.578, 3.482, 2.592 and 2.253 mg·g -1 in acidic conditions.
