| 中文摘要 | polydopamine coated sea buckthorn branch powder (pda@sbp) was facilely synthesized via a one-pot bio-inspired dip-coating approach. the as-synthesized pda@sbp was characterized using fourier transform infrared (ftir) spectroscopy and scanning electron microscopy (sem). the adsorption progresses of safranine t on the surface of pda@sbp adsorbent were systematically investigated. more specifically, the effects of solution ph, contact time, initial concentration and temperature were evaluated, respectively. the experimental results showed the adsorption capacity of pda@sbp at 293.15 k could reach up to 54.0 mg/g; the adsorption increased by 201.7% compared to that of native sbp (17.9 mg/g). besides, kinetics studies showed that pseudo-second-order kinetic model adequately described the adsorption behavior. the adsorption experimental data could be fitted well a freundlich isotherm model. thermodynamic analyses showed that the st adsorption was a physisorption endothermic process. regeneration of the spent pda@sbp adsorbent was conducted with 0.1 m hcl without significant reduction in adsorption capacity. on the basis of these investigations, it is believed that the pda@sbp adsorbent could have potential applications in sewage disposal areas because of their considerable adsorption capacities, brilliant regeneration capability, and cost-effective and eco-friendly preparation and use.
