Abstract Various polymers were systematically screened as matrices for H2TiO3 Li+ adsorbent. H2TiO3/polymers were electrospun as nanofibers (NF), characterized, and evaluated via response surface methodology with central composite design for Li+ adsorption experiments. Polyacrylonitrile (PAN) was determined as the most suitable H2TiO3 support. H2TiO3/PAN hydrophilicity and its favorable NF structure provided sufficient feed interaction. The Li+ adsorption was Langmuir-type with maximum capacity = 72.75 mg g−1 and adsorption rate = 1.89 × 10−4 g mg−1 min−1. H2TiO3/PAN is Li+-selective, with a thermodynamically favorable adsorption. Stable performance and durability during cycled adsorption/desorption runs prove H2TiO3/PAN NF as highly effective composite Li+ adsorbent.

从 H2TiO3/聚合物纳米纤维复合材料开发高容量 Li+ 吸附剂：系统聚合物筛选、表征和评估

摘要 系统地筛选了各种聚合物作为 H2TiO3 Li+ 吸附剂的基质。H2TiO3/聚合物被电纺成纳米纤维（NF），通过响应面方法和中心复合设计进行表征和评估，用于Li+吸附实验。聚丙烯腈 (PAN) 被确定为最合适的 H2TiO3 载体。H2TiO3/PAN 亲水性及其有利的 NF 结构提供了足够的进料相互作用。Li+ 吸附为朗缪尔型，最大容量 = 72.75 mg g-1，吸附速率 = 1.89 × 10-4 g mg-1 min-1。H2TiO3/PAN 是 Li+ 选择性的，具有热力学有利的吸附。在循环吸附/解吸运行期间的稳定性能和耐用性证明 H2TiO3/PAN NF 是高效的复合 Li+ 吸附剂。
