摘要

利用壳聚糖和硅酸钠溶液，通过相反转法合成了膜。本研究旨在表征竹叶二氧化硅壳聚糖膜（SCM），并确定合成产品对铅（II）离子的吸附能力。XRF 表征显示，竹叶中的二氧化硅含量为 78.03%。吸附前的扫描电镜分析结果约为 13.0 μm，吸附后的孔径约为 9.7 μm。使用 AAS 对金属铅（II）的吸附分析结果表明，当吸附的金属铅（II）初始浓度为 10.0000 ppm 时，单片机变化 A 为 9.8101 ppm，当吸附的金属铅（II）初始浓度为 25.0000 ppm 时，单片机变化 A 为 22.3421 ppm。初始浓度为 10.0000 ppm 时，吸附的铅（II）金属变化 B 为 9.8870 ppm，初始浓度为 25.0000 ppm 时，吸附的铅（II）金属变化 B 为 23.5806 ppm。初始浓度为 10.0000 ppm 时，吸附的铅（II）金属的变化 C 为 9.9639 ppm，初始浓度为 25.0000 ppm 时，吸附的铅（II）金属的变化 C 为 24.1855 ppm。研究结果表明，单片机吸附力最高的是变体 C（2%:22.95%），吸附率为 99.63%。

Synthesis of Chitosan Silica Membrane from Petung Bamboo (Dendrocalamus asper) Leaves and Its Application as Pb(II) Metallic Adsorbent

Membrane synthesis through a phase inversion method using chitosan and sodium silicate solutions has been conducted. This research aims to characterize the silica chitosan membrane (SCM) of petung bamboo leaves and determine the synthesized product's adsorption capacity for Pb(II) ions. The XRF characterization showed the silica content of petung bamboo leaves with a percentage of 78.03%. SEM analysis before adsorption is around 13.0 μm, and the pore diameter after adsorption is around 9.7 μm. The results of adsorption analysis of Pb(II) metal using AAS showed that the SCM variation A at an initial concentration of 10.0000 ppm Pb(II) metal adsorbed was 9.8101 ppm, and at an initial concentration of 25.0000 ppm Pb(II) metal was 22.3421 ppm. The variation B at an initial concentration of 10.0000 ppm Pb(II) metal adsorbed was 9.8870 ppm and at an initial concentration of 25.0000 ppm Pb(II) metal adsorbed was 23.5806 ppm. The variation C at an initial concentration of 10.0000 ppm Pb(II) metal adsorbed was 9.9639 ppm, and at an initial concentration of 25.0000 ppm Pb(II) metal was 24.1855 ppm. The results of this research conclude that the highest SCM adsorption power is variation C (2%:22.95%) with a percentage of 99.63%.
