Natural zeolite is widely used in removing ammonia via adsorption process because of its superior ion-exchange properties. Ceramic particle size affects the adsorptivity of particles toward ammonia. In this study, hollow fiber ceramic membrane (HFCM) was fabricated from natural zeolite via phase inversion. The effect of natural zeolite particle size toward the properties and performance of HFCM was evaluated. The results show that the HFCM with smaller particle sizes exhibited a more compact morphological structure with better mechanical strength. The adsorption performance of HFCM was significantly improved with smaller particle sizes because of longer residence time, as proven by the lower water permeability. A high adsorption performance of 96.67% was achieved for HFCM with the smallest particle size (36 μm). These findings provide a new perspective on the promising properties of the natural zeolite-derived HFCM for ammonia removal.
天然沸石因其优异的离子交换性能而被广泛用于通过吸附过程去除氨。陶瓷颗粒尺寸会影响颗粒对氨的吸附性。在本研究中，通过相转化法由天然沸石制备了中空纤维陶瓷膜（HFCM）。评估了天然沸石颗粒尺寸对HFCM性能和性能的影响。结果表明，颗粒尺寸较小的HFCM呈现出更致密的形态结构，具有更好的机械强度。由于停留时间更长，颗粒尺寸较小的HFCM的吸附性能显著提高，较低的水渗透性证明了这一点。颗粒尺寸最小（36μm）的HFCM实现了96.67%的高吸附性能。这些发现为天然沸石衍生的HFCM在氨去除方面的潜在性能提供了新的视角。
