摘要

以柚子叶提取物为原料，采用生物合成法在0.05、0.1和0.5 M的不同前体浓度下合成ZnO纳米颗粒。纳米颗粒初始浓度影响了光学带隙、形状和结构。在紫外光照下进行了光降解过程。通过测定MB浓度的下降量和紫外-可见光谱记录的663 nm处的光吸收来确定MB的降解效率。结果表明，生物合成的ZnO纳米粒子对MB具有良好的光降解能力，在UV-C光照射90分钟后，其降解率最高可达80%。该研究强调了柚子叶提取物作为一种低成本、环保的ZnO纳米颗粒合成替代品的潜力，并将其用于环境修复过程

Investigating the Influence of Precursor Concentration on the Photodegradation of Methylene Blue using Biosynthesized ZnO from Pometia pinnata Leaf Extracts

The ZnO nanoparticles were synthesized at various precursor concentrations i.e. 0.05, 0.1, and 0.5 M by biosynthesis method based on Pometia pinnata Leaf Extracts. Initial nanoparticle concentration influenced the optical bandgap, shape, and structure of nanoparticles. The photodegradation process was carried out under UV illumination. The efficiency of MB degradation was determined by measuring the decrease in MB concentration and by analyzing the optical absorption at 663 nm recorded by UV-Vis spectroscopy. Results showed that the biosynthesized ZnO nanoparticles exhibited efficient photodegradation of MB, with a maximum degradation rate of 80% after 90 minutes of exposure to UV-C light. The study highlights the potential of Pometia pinnata leaf extracts as a low-cost and eco-friendly alternative for synthesizing ZnO nanoparticles for use in environmental remediation processes
