Abstract

Our previous work had demonstrated that UV/NaClO was the best advanced oxidation method in terms of nitric oxide (NO) removal, but we have not studied the impact of the fly ash on NO removal under such conditions. For this, this paper selected six kinds of fly ashes and studied their effects on NO removal. The micromorphology, elemental composition, and the elemental oxidation states of these six fly ashes were characterized by scanning electron microscopy-energy-dispersive X-ray spectra, X-ray photoelectron spectroscopy, and inductively coupled plasma methods. The main inorganic components in the six fly ashes are metal oxides (FeO/FeO, SiO, AlO, ZnO, MgO, and TiO), carbonates (NaCO and CaCO), and chlorides (NaCl, KCl, and MgCl). The experimental results suggested that high solubility was the premise condition for the fly ashes exhibiting an inhibitory effect on NO removal. Among all of the metal compounds, FeO/FeO exhibited the highest inhibitory contribution rate to the NO removal (22.9-45.7%). The anions of Cl and CO acted as scavengers for the free radicals which greatly impaired the oxidation of NO. Based on the simulation experimental results and the UV-vis analysis, the order of inhibitory contribution rates of various metal compounds to the NO removal was determined as FeO/FeO > TiO ≈ NaCO > AlO ≈ ZnO ≈ MnO > CaCO > NaCl > KCl ≈ SiO ≈ MgCl.

摘要

我们之前的工作已经证明，就一氧化氮（NO）去除而言，UV/NaClO是最佳的高级氧化方法，但我们尚未研究在这种条件下粉煤灰对NO去除的影响。为此，本文选取了六种粉煤灰并研究了它们对NO去除的影响。通过扫描电子显微镜-能量色散X射线光谱、X射线光电子能谱和电感耦合等离子体方法对这六种粉煤灰的微观形态、元素组成和元素氧化态进行了表征。六种粉煤灰中的主要无机成分是金属氧化物（FeO/Fe₂O₃、SiO₂、Al₂O₃、ZnO、MgO和TiO₂）、碳酸盐（Na₂CO₃和CaCO₃）以及氯化物（NaCl、KCl和MgCl₂）。实验结果表明，高溶解度是粉煤灰对NO去除表现出抑制作用的前提条件。在所有金属化合物中，FeO/Fe₂O₃对NO去除的抑制贡献率最高（22.9 - 45.7%）。Cl⁻和CO₃²⁻阴离子作为自由基清除剂，极大地削弱了NO的氧化。基于模拟实验结果和紫外可见分析，确定了各种金属化合物对NO去除的抑制贡献率顺序为FeO/Fe₂O₃ > TiO₂ ≈ Na₂CO₃ > Al₂O₃ ≈ ZnO ≈ MnO > CaCO₃ > NaCl > KCl ≈ SiO₂ ≈ MgCl₂。
