Extraction of lithium from liquid lithium resources has become a popular research field, among which H₂TiO₃ material has great application potential. In this work, we further explored the correlation that the hydrophilicity of H₂TiO₃ with its adsorption performance based on the existing work. The double surfactants method was used to regulate the morphology and hydrophilic functional groups of the surface to regulate the material hydrophilia and prepare nano-sized lithium ion sieve. The effect of surfactant and preparation method on the hydrophilicity and adsorption properties of the materials were investigated. The results show that the synthesized lithium ion sieve H₂TiO₃-4 (HTO-4) has excellent hydrophilicity and adsorption performance reflected with the maximum adsorption capacity of 56.03 mg·g^-1. Meanwhile, the adsorption capacity loss of the material is only 3.8% after five cycles, which shows a satisfactory cyclic stability.

从液态锂资源中提取锂已成为热门研究领域，其中H ₂ TiO ₃材料具有很大的应用潜力。在这项工作中，我们在现有工作的基础上进一步探讨了H ₂ TiO ₃的亲水性与其吸附性能的相关性。采用双表面活性剂法调控表面形貌和亲水官能团，调控材料的亲水性，制备纳米尺寸的锂离子筛。考察了表面活性剂和制备方法对材料亲水性和吸附性能的影响。结果表明，合成的锂离子筛H ₂ TiO ₃-4（HTO-4）具有优异的亲水性和吸附性能，最大吸附量为56.03 mg·g ^-1。同时，5次循环后材料的吸附容量损失仅为3.8%，表现出良好的循环稳定性。
