Rezumat

Four series of samples containing manganese supported carbonaceous adsorbents were prepared. Samples of series AC-B, synthesised from the carbonaceous support with basic surface, were obtained with a yield of 50-60%, while manganese was loaded in amount of 1.44-1.65 % depending on applied method. The samples of series AC-A, synthesised from the carbonaceous support with acidic surface, were obtained with a higher yield (92-98%), but with small quantities of loaded manganese. Obtained results reveal the importance of surface chemistry of carbonaceous adsorbents on the manganese loading.
