With advancement of technologies in most of the sectors, the market requirement for the rare earth elements (REEs) increasing at a rapid rate. Hence, it is vital to recover REEs from wastewater. Thus, in the present study, biosorptive uptake of praseodymium (Pr(III)) and thulium (Tm(III)) ions from mono and binary solutions using polysulfone-immobilized Turbinaria conoides (PITC) were examined for the first time The sorption of Pr(III) and Tm(III) ions were performed in batch and column biosorption systems. The biosorptional uptakes of PITC for Pr(III) and Tm(III) in mono solution were found as 1.14 and 1.23 mmol/g, respectively. The equilibrium biosorption data of the mono system were examined through the Langmuir and Freundlich isotherms, whereas data of binary biosorption experiments were checked with Sheindorf–Rebhun–Sheintuch and extended Langmuir isotherm model. The desorption efficiency of PITC in batch system showed recovery of Pr(III) and Tm(III) more than 95.5% up to 5 cycles. Continuous biosorption models like the Thomas, Yoon–Nelson and modified dose–response were employed to understand continuous biosorption behavior, and model constants were determined. The column desorption efficiency were observed as 98.9% (Pm(III)) and 99.5% (Tm(III)). Good biosorption capacity, desorption and reuse potential of PITC illustrated the environmental friendliness and scalable features.

随着大多数行业中技术的进步，稀土元素（REE）的市场需求迅速增长。因此，从废水中回收稀土元素至关重要。因此，在本研究中，使用固定化聚砜的Turbinaria固形物从单溶液和二元溶液中吸收take（Pr（III））和th（Tm（III））离子首次检查了PITC（PITC）。Pr（III）和Tm（III）离子的吸附是在间歇式和柱式生物吸附系统中进行的。发现在单一溶液中PITC对Pr（III）和Tm（III）的生物吸附吸收分别为1.14和1.23 mmol / g。通过Langmuir和Freundlich等温线检查了单系统的平衡生物吸附数据，而使用Sheindorf–Rebhun–Sheintuch和扩展的Langmuir等温线模型检查了二元生物吸附实验的数据。分批系统中PITC的解吸效率显示，在5个循环内，Pr（III）和Tm（III）的回收率均超过95.5％。采用连续生物吸附模型（例如Thomas，Yoon-Nelson和修改后的剂量反应）来了解连续生物吸附行为，并确定了模型常数。观察到柱解吸效率为98.9％（Pm（III））和99.5％（Tm（III））。PITC的良好的生物吸附能力，解吸和再利用潜力说明了其环境友好性和可扩展性。
