Sažetak
The study focuses on the synthesis of two adsorbent forms that were prepared: magnetic nonporous hybrid beads (MNPHB), and magnetic macroporous hybrid beads (MMPHB). The salicylic acid adsorption tests on MNPHB and MMPHB were carried out at a temperature of 25 °C, pH 4, adsorbent mass of 10 mg, and an initial concentration of 10 mg l–1. The adsorption capacity was found to be for MNPHP and MMPHB to 9 mg g–1 and 152 mg g–1, respectively. The adsorption kinetic was described by the pseudo-second order model and Freundlich isotherm for the MMPHB beads.
