Optimum özelliklere sahip manyetik nanobiyokompozit adsorban ile toryumun sulu çözeltilerden uzaklaştırılması için, pH, toryum konsantrasyonu, sıcaklık ve temas süresi gibi ana deneysel parametrelerin etkisi kesikli yöntemlerle incelenmiştir. Langmuir, Freundlich ve Dubinin-Radushkevich izotermleri kullanılarak adsorpsiyon modeli belirlenmiş ve ilgili parametreler hesaplanmıştır. Ayrıca, adsorpsiyonun termodinamik parametreleri olan entalpi, Gibbs serbest enerji değişimi ve entropi hesaplanmıştır. KW - Pektin KW - Nanobiyokompozit KW - Toryum KW - Adsorpsiyon N2 - In this study, effective, safe, environmentally friendly and non-toxic pectin-magnetic (Fe3O4) nanobiocomposites were synthesised and characterised by co-precipitation method for the removal of thorium from aquatic environments. The effect of main experimental parameters such as pH, thorium concentration, temperature and contact time on the removal of thorium from aqueous solutions by magnetic nanobiocomposite adsorbent with optimum properties was investigated by batch methods. The adsorption model was determined using Langmuir, Freundlich and Dubinin-Radushkevich isotherms and the related parameters were calculated. In addition, the thermodynamic parameters of adsorption such as enthalpy, Gibbs free energy change and entropy were calculated. CR - [1] Nyberg, A. G., Stricklin, D., Sellström, A., 2011.
