摘要: Abstract Mixtures of sewage sludge and fish waste various compositions were prepared pyrolyzed at 950 °C in an inert atmosphere. On the samples activation with CO2 was carried out 850 °C. The materials used as H2S adsorbents ambient conditions. Initial spent characterized using thermal analysis, XRD, XRF, SEM/EDX, sorption nitrogen surface pH measurements. An enhancement removal capacity on composite linked to synergistic effects chemical composition. adsorbents’ reactivity presence Na, K, Ca, Mg Fe configurations. Activation had a detrimental effect composites’ performance H2S. component provides active iron phase, which is important for hydrogen sulfide oxidation. Potassium sodium polysulfides sulfite, sulfate, are products reactive adsorption. strongest found lowest content component. With increase this diminishes owing reactions alkaline metals silica during pyrolysis.
