摘要
通过元素分析、x射线衍射相分析、红外光谱分析和pH-metry对两种类型的电极(no -4和TsL-11)金属焊接得到的焊接气溶胶(SCWA)固体组分样品进行了表征。scwa - ono -4和SCWA-TsL-11样品均可将臭氧浓度为1.0 mg/m3的臭氧-空气混合物(OAM)净化至0.1 mg/m3以下(最大允许臭氧浓度MPCO3)。
Nanostructured materials based on the solid component of welding aerosol as catalysts for low-temperature ozone decomposition
Samples of the solid component of welding aerosol (SCWA) obtained as a result of metal welding by two types of electrodes, ANO-4 and TsL-11, were characterized by elemental analysis, X-ray diffraction phase analysis, IR spectroscopy, and pH-metry. Both SCWA-ANO-4 and SCWA-TsL-11 samples purified the ozone-air mixture (OAM) with ozone concentration of 1.0 mg/m3 to the concentration values below 0.1 mg/m3 (maximum permissible ozone concentration, MPCO3).
